Installing fasteners during the stamping process PennEngineering highlights that its PEMSERTER In-Die Fastener Feeding System is uniquely engineered to install self-clinching nuts, studs, and standoffs in assemblies during the stamping process. ®

W

orking in tandem with a stamping press (and properly tooled die) to feed and install fasteners, the portable PEMSERTER ® In-Die Fastener Feeding System eliminates secondary operations typically required for fastener insertions.

PennEngineering points out that this means users can realise increased assembly-line productivity, quality, and savings as two operations (stamping and fastener installation) can be performed simultaneously in the die.

The PEMSERTER In-Die Fastener Feeding System is virtually “plug and play” by utilising multi-pin twist lock connectors to interface with the die and stamping press. The system can be configured for multiple or single insertions, generally matching the rate of the stamping press.

Operators are guided by a touch-screen (for set-up and operation) and online library of fault/help screens. Removable tooling can handle complex workpieces and offers considerable adaptability capable of reaching into areas generally considered inaccessible. Customised tooling can also be engineered to meet particular application needs.

“The In-Die Fastener Feeding System consists of die tooling, fastener-feeding system, and die-sensing system. Customers are fully supported from die design through installation and in-house training.”

RotaBolts for live pipeline intervention RotaBolt measurement technology is now being used by GL Noble Denton on all its live onshore pipeline intervention systems, which have been developed to allow operators to maintain gas and oil flows during major pipeline work.

R

otaBolt ® fasteners up to M64 size are being fitted on the company’s ‘grouted tees’ originally developed for intervention work on gas transmission pipelines in the National Grid, but now being used further afield in Brazil, Norway and Kazakhstan.

Traditionally, when pipeline flows had to be either diverted or repaired, a welded tee connection was used to make the intervention, causing lengthy and costly interruptions to production. The grouted tee system was developed as a safe and quick method of intervention for high and low pressure pipelines of varying diameters.

“We have switched to using RotaBolts because they are giving us the operational assurance we are looking for,” commented Anthony Wood, senior consultant for Asset Management at GL Noble Denton. “They are simple to install, easy to monitor and give us a

highly accurate measurement of tension across the joint.

Feedback from everyone has been very positive.”

Each grouted tee piece is custom manufactured to the appropriate size and is made up of two half-shells which are then RotaBolted around the host pipe. A special rubber seal is installed and retained in position by a steel containment ring inside the half shell within the tee piece.

Opposite the branch in the other half shell, spreader plates are located to allow seal compression during the tightening process. Once the half shells have been clamped around the host pipe and the RotaBolts tightened to the predesigned load, the gaps between the ends of the half shells and the host pipe are filled with rapid-setting epoxy putty as a seal.

An epoxy grout is then injected to fill the space between the inside of the tee

8 Fastener + Fixing Technology • Issue 4 Jan - Mar 2012

piece and the host pipe. This adheres to both surfaces to keep the tee securely in place and also transfers the load from the main pipe to the newly-installed outer shell.

Solutions using this technique have also been developed for installing multiple branch tees of similar or different sizes, and for diver-installed use of the technology subsea. The grouted tee is suitable for operations with numerous pipeline fluids and gases in the temperature range –50°C to +125°C, and can be manufactured to suit a host pipe diameter from 2 inches to 56 inches.

Marking genuine Phillips drive quality Richard Spence, marketing and sales director for Phillips in Europe, explains the company’s history and looks to the future.

A

The history of Phillips Screw Company

sk anyone in industry if they have heard of a ‘Phillips Screw’ and it is likely that they would have. In fact, the name Phillips, when applied to a screw specifically, is one of the world’s most recognised product names, which is some achievement when, in reality, there are no Phillips-branded screws!

The Phillips Screw Company designs and builds the essential technologies that serve as a foundation and quality benchmark for the world’s fasteners. Generations of builders, craftsmen, industry workers and D.I.Y. enthusiasts have come to appreciate the value of a quality drive system and, for more than 75 years, Phillips has been developing and improving these systems for screws. From the original cross recess to today’s enhanced drives, such as the Pozisquare ® drive using stick-fit/stable-drive technology, Phillips has been a consistent leader in innovation.

Today, the company continues to improve and evolve drive systems that are used throughout industry. Phillips technology can be found in virtually every aeroplane, vehicle, building and electronic device and the company is firmly associated with key industry terms like ‘technological leadership’, ’quality’, ’high torque transfer’ and ’reliability’.

This leadership in innovation, however, can lead to issues within the industry that need to be monitored. Once a

technology becomes ‘generic’ for example, it is opened up to unmonitored copies where production standards diverge from the original recess, resulting in poorer specifications and assurance of quality can suffer. To combat this, Phillips has now introduced the ‘Genuine Phillips Drive System’ programme to demonstrate that the recesses have been produced and gauged to stringent standards.

To reinforce this message, all products with genuine Phillips recesses will be clearly labelled with a ‘Genuine Phillips’ hologram on the packaging, giving the user the confidence that it has been produced to the approved standard. As more people become aware of the ‘Genuine Phillips’ logo, and the guarantee it offers, they will be confident that they are buying and using the best.

In order to correctly communicate the benefits of fasteners with Phillips patented and quality controlled technology, the company has invested significantly in developing and protecting state of the art technology and more in delivering performance and reliability credentials with the quality assurance logo.

Consequently we are communicating a stronger ‘mark of quality’ image to our consumers, distinguishing a Phillips quality assured product that is clearly identifiable from the competition. www.phillips-screw.com

John P. Thompson granted United States patent for a revolutionary cruciform drive system that will lay the foundation for the original Phillips® fastener drive system.

Henry F. Phillips, founder of the Phillips Screw Company, purchases the rights to the Thompson patent. He then modifies the Thompson patent to make the cruciform drive system adaptable to mass production.

The Cadillac division of General Motors begins assembling all automobile models with the new Phillips screw system.

International Standards Organisation (ISO) in Geneva, Switzerland, recognises the ACR Torq-Set drive system as an international standard.

Phillips Screw Company establishes a European division to provide marketing support for its existing base of European Union licensees and establishes distribution operations.

Phillips Screw Company and W. Dodd Stacy of Creare, Inc. conclude an agreement that gives Phillips the exclusive rights to license the newly patented Mortorq®.

POZISQUARE® DRIV - the multinational drive solution The POZISQUARE ® DRIV combination drive system is the best of two fastening worlds. The screw can be driven with a POZISQUARE DRIV® driver, a plain “square” or Canadian “square drive system”, or common Phillips drivers.

POZISQUARE DRIV® offers a consistent stick between the driver and screw, making working on hard to reach joints simple and reducing worker fatigue. It also increases productivity, minimises screw damage and extends drive tool life.

Driver sizes: 0-1 thru 3-3

Screw sizes: M3 (#4) thru M6 (¼ inch)

HEXSTIX® - The stable drive system The HEXSTIX® stable drive system increases speed and efficiency in one-handed applications of assembled components. The screw recess design has an outstanding ability to hold firmly to the driver bit at the point of assembly — with no magnetic bits or vacuum screw holders required.

Engineered to deliver superior stability and axial alignment HEXSTIX® enables the operator to start the screw more easily and reduce the risk of cross threading.

Secure engagement of the screw recess to the driver bit maintains backwards compatibility to generic 6-lobe screws.

For maintenance and field use, standard driver bits can be used to remove or replace HEXSTIX® screws.

Driver sizes: H15 thru H50

J.J. Tomalis, an American Screw engineer, incorporates a patented improvement into the Phillips drive system and the new screw is recognised as the official Phillips standard.

A new higher torquing off-set cruciform drive system is patented, which Phillips begins licensing to aerospace fastener manufacturers under the trade styles, Torq-Set® and Tri-Wing®.

Screw sizes: M3.5 (#6) thru M10 (7/16 inch)

Guest, Keen & Nettlefolds buys the worldwide patent and trademark rights to the Pozidriv fastener system outside of North America.

2012 Phillips purchases Wrentham Tool Products LLC in order to provide its global fastener licensees access to a broad line of both proprietary and generic fastener tooling and gauging.

Phillips’ sister company Wrentham Tool Products expands manufacturing facility with the Rico/Astro Punch manufacturing acquisition.

The importance of recess and screw quality is emphasised with the introduction of the ‘Genuine Phillips Quality’ hologram on boxed fasteners and as a logo in catalogues.

automotive + corrosion

Rigorously implemented

By Rudolf Knott, Central Engineering Division, MAN Truck & Bus A, & Dr. Jochen Schneider, Customer Service, Dörken MKS-Systeme GmbH & Co. KG Commercial vehicle manufacturer MAN will from now on be using a chrome (VI)free coating from Dörken for the surface protection of high-strength steel fasteners.

Its layered structure made up of a zinc flake coating with coordinated postlubrication achieves the specified high level of corrosion resistance and fulfils at the same time the coefficient of friction requirements.

M

AN Truck & Bus AG of Munich is the largest company in the MAN Group and one of the world’s leading suppliers of commercial vehicles and transportation solutions. As a pioneer in all areas of relevant technology, the company is constantly looking for new solutions to reduce fuel consumption, exhaust emissions and noise level. The MAN TGX 18400, for example, received the ‘Green Truck 2011’ award, having impressed judges with the lowest level of fuel consumption and CO2 emissions on the European market.

However, ecological accomplishments have taken a high priority at the company for many years. Regular internal and external audits are, for example, run at every production site in order to review the environmental protection measures in place and to continually improve the company’s sparing use of water and material resources and the reduction in air pollutants. Some of these measures are concerned, for instance, with reducing

12 Fastener + Fixing Technology • Issue 4 Jan - Mar 2012

use of coolants and lubricants and the associated consumption of water, while others relate to optimising fasteners’ anticorrosion coating from a ‘green’ perspective.

Responsible decision making Although EU Directive 2000/ 53/EC, which has been in force since July 2007, does not apply to vehicles over 3.5 tonnes, MAN decided to switch surface coatings for all bolts and other fasteners to chrome (VI) -free alternatives. This decision was, of course, taken partly to reduce the risks to humanbeings and the environment. However, commercial and logistical considerations also played a part.

That’s due to the fact that at every stage of the production process right through to assembly chrome (VI) -free parts have to be strictly separated from parts with a chrome (VI) content. A duplicated production line would also mean higher logistical and manufacturing costs. Furthermore, since the EU End-of-Life Vehicle Directive came into force coatings with chrome (VI) content are becoming less and less available and therefore also more expensive.

In search of alternatives for the previously used systems consisting of coatings with chrome (VI) content and postlubrication, the company quickly became aware of Dörken MKS-Systeme GmbH & Co. KG from Herdecke. Dörken’s zinc flake systems have not only been chrome (VI) -free from the outset, but through the company’s close contacts with many representatives of the value-added chain, it was also possible to link up quickly with an international fastener manufacturing company, which was then incorporated into the early discussions. The aim here was to specify the parts provided for extensive test cycles and to define all key additional factors, such as fastening parameters and bearing surfaces. The parts tested were high-strength steel bolts and nuts ranging in size from M12 to M16. In addition to resistance

automotive + corrosion to base metal corrosion of at least 720 hours, the lubricant effect demanded by MAN was also particularly important in order to also ensure smooth fitting of such parts in practice.

Various zinc flake based Cr(VI) -free coating systems that had been tested had not been able to satisfactorily fulfil the coefficient of friction requirements.

A jointly devised system based solution Against the background of MAN’s specifications, coating experiments were run using two selected systems in the pilot plant at the Herdecke site. The coating patterns were tested both at Dörken and at the fastener manufacturer’s premises, using the tests that had been previously jointly defined. In the subsequent assessments a solution already began to crystallise, based on a zinc flake coating and a customised form of post-lubrication. In further tests it was possible to confirm the new coating’s functionality.

all standard application methods. Which method to choose depends on the size and shape of the parts. In MAN’s case parts of smaller dimensions are being coated using the dip spin process (pictured below), while for bolts > M16 spin coating has proved the most cost-effective method. After coating and preliminary drying, the protective coat gets cured for an average of 30 minutes with the part at temperatures of 200°C to 250°C. Subsequently a new form of post-lubrication with multifunctional properties is applied using Delta-Lube ® 10. The material has been specifically designed for mass-produced parts that are assembled using automatic bolting systems.

It produces a dry lubricant coat and ensures constant overall coefficients of friction with a value based by MAN on the VDA range of between 0.09µg and 0.14µg. For the user that means predictable and - in relation to tightening torque and clamping force - reproducible results and shorter assembly times. The post-lubrication also gets applied by the dip spin process or spin

The fasteners are coated using the dip and centrifuge process The basecoat selected, Delta-Protekt ® KL 100, provides active cathodic protection and with a coating thickness of just 10µm achieves – dependent upon layer build-up, shape of the parts and form of application – corrosion resistance times as defined by DIN EN ISO 9227 of up to 1,000 hours. Another factor of importance for use on high-strength steel fasteners is that as no hydrogen is introduced in the coating process, any danger of hydrogen embrittlement caused by the process can be confidently ruled out. The coating can be applied in

14 Fastener + Fixing Technology • Issue 4 Jan - Mar 2012

coating and then gets dried for approximately 15 to 20 minutes at 50°C to 60°C. In order to reliably identify the newly coated parts, the new post-lubrication has a greenish colour.

The whole concept has to be right The new coating structure has now been approved by MAN as part of the MAN 183 company norm. Key factors for this global player in the commercial vehicles industry were not just the technical features of the solution, but also Dörken MKS Systems’ global presence through a system of local subsidiaries and the application of the products by licensed coating companies, which using coordinated application techniques achieve the same high quality of coating results all over the world. Application advice is provided

by Dörken MKS employees in all major European markets and in addition to the large technology centre in Herdecke there are also tech centres available in the USA, South Korea and – particularly important for MAN – in the growth markets of Brazil and China. An expert contact is therefore always close at hand. www.doerken-mks.com

bigHead fasteners solve corrosion problems bigHead has developed an innovative solution for a key contractor to major offshore Oil & Gas installations. Secure and versatile, the bigHead fasteners are installed on downward facing steel surfaces to hold safety critical insulation materials in position over long periods of time without corroding.

A

critical objective for the client was to move away from welded pins which suffer from corrosion in severe offshore climates. When securing insulation and fire protection systems in place such corrosion jeopardises safety and necessitates costly repairs and maintenance.

The bigHead butterfly bracket utilises bigHead’s unique design to avoid welding and allow simple surface bonding with adhesive. In this particular example the bigHeads were surface bonded into position with a new structural adhesive from 3M. Once installed, the bigHead fastener provides a secure fixing

for the application of a wet applied insulation material. bigHead highlights that it was able to come up with design prototypes within days of the enquiry coming in from the Oil & Gas contractor. Due to its unique process bigHead was also able to provide multiple designs in a short space of time and also test the strength of those designs for the client.

“Made with 316 stainless steel the bigHead butterfly bracket is resistant to the most severe marine climates.

This type of application specific design for technical clients is something that we at bigHead have been specialising in for over 40 years.”

Streamlining automotive coating requirements The number of coatings available to automotive fastener engineers keeps growing. Drivers such as increased performance, friction properties, robustness in use and environmental compatibility have led to more choice; but is more choice always a good thing? How does an engineer make that choice?

Does a vehicle need so many different fastener coatings? Here MacDermid Inc explains why it believes the opposite is now more preferable - less choice and one coating which meets all the needs.

Zinc-nickel, the coating which is gaining new advocates High alloy (15% Ni) zinc-nickel’s popularity has grown to such an extent that an engineer will now consider it directly alongside contemporary finishes such as organic (paint) and (pure) zinc electroplate coatings. Whereas these two coatings have limitations when assessed against the primary drivers, zinc-nickel meets all the requirements.

Electroplate, long considered as the bulk sacrificial coating of choice, has a real advantage in delivering a coating which respects even the finest dimensional tolerances of fasteners.

However pure zinc electroplate does not meet the higher corrosion (neutral salt spray) requirements of many modern automotive specifications.

On the other hand painted coatings, which meet the tougher neutral salt spray demands, are not usually employed when coating the smaller bolt or screw sizes due to the risk of head and thread fill.

So we come back to zinc-nickel. With a neutral salt spray resistance in excess of 1,000 hours, it competes with any other commercially available mass fastener coating. Being electroplated it respects even the finest dimensional tolerance, has a high hardness (450HV) and has exceptional adhesion.

The growing use of self threading fasteners means that a coating which retains adhesion during assembly process is critical. Unlike other coatings, zinc-nickel won’t gall or lift during the tapping and tightening process. Additionally it can be specified in both black

16 Fastener + Fixing Technology • Issue 4 Jan - Mar 2012

or silver (without the need for a heavy painted topcoat).

Application of a thin film dry film lubricant provides friction properties which can be tailored to the OEM specification demands. This dry film (often referred to as a topcoat) also provides abrasion resistance. Good abrasion resistance is required to maintain the coating properties during vehicle assembly, where processes such as vibratory automated line feeds subject fasteners to high abrasion. Finally being free of hexavalent chromium compounds these coatings meet ELV and RoHS directives.

In summary some engineers are looking at zinc-nickel as being an effective way to reduce the number of finishes required to achieve high fastener service life performance and reduce coating variability by streamlining their fastener supply chain.

New guide to Spirol compression limiters Spirol Industries says that its compression limiters are the ideal components to meet the specific engineering and cost objectives for manufacturers of plastic assemblies.

S

pirol’s standard range of compression limiters will meet most requirements, but special diameter, length, duty, material, tolerance configurations can also be supplied.

The company’s new compression limiter design guide provides details of all the product options available, design considerations and information on the support services available from Spirol Industries.

Compression limiters are designed to protect the plastic components of an assembly from the compressive loads generated by the tightening of bolts and will ensure the continued integrity of the bolted connection. As the bolt is tightened the plastic compresses and the stress in the plastic increases until the head of the bolt comes into contact with the compression limiter. The compression limiter and plastic will

compress at the same rate with the limiter absorbing additional clamping loads, without increased stress in the plastic material.

The Spirol compression limiter range includes the moulded-in, split seam and solid knurled designs. The moulded-in type is produced from low carbon steel and is equipped with radial grooves to provide maximum retention. The split seam type is produced from low carbon and high carbon steel. The solid knurled type is produced from brass and aluminium.

Starting with an analysis of a customer’s manufacturing and cost objectives, Spirol application engineers determine the most suitable compression limiter, considering the specifications of the components to be assembled and implications for their assembly.

Polyurethane matrix resin for automotive composites With lightweighting in mind, automotive manufacturers are using more and more parts made from carbon fibre or glass fibre composites. Henkel has developed a polyurethane-based composite matrix resin that cures faster than the traditional epoxy resins.

C

omposites based on carbon fibre or glass fibre are gaining momentum in various application areas due to the opportunity for enormous weight savings over traditional part construction, with no loss in mechanical performance.

Starting in aerospace where pre-impregnated fibres (prepregs) are manually laid up and then baked into composites, many different applications are now penetrating into the automotive industry. New manufacturing methods like resin transfer molding enable economic processes that are suited for high volume automotive production.

For the resin transfer molding process, Henkel has developed

18 Fastener + Fixing Technology • Issue 4 Jan - Mar 2012

a new composite matrix resin based on polyurethane which enables improved economics and throughput in processing.

Compared to standard epoxy matrix resins, the new Loctite MAX2 cures significantly faster. During injection, it also enables more efficient impregnation without stressing the fibres due to the lower viscosity of the resin.

The composite properties of Loctite MAX2 were specially developed to provide more flexibility as well as much higher impact resistance than traditional epoxy resins. Henkel is confident that this new generation of polyurethane matrix resins deliver significant benefits for fast and efficient manufacturing.

awlplug was invented by British engineer John J. Rawling in the year 1910. By the end of World War I in 1918, there were huge demands for repair work all over Europe. In order to meet these demands the Rawling brothers started large-scale production in 1919. In the same year, Rawlplug was registered as a brand and patented as the first ever specialist wall fixing. John J. Rawling’s revolutionary Fibre Plug was the product from which the modern range of Rawlplug fixings was to develop.

By 1920s Rawlplug gained its fame in the countries ruled by the British, one of which was India. Several of the great Indian projects were commissioned under British rule with Rawlplugs being used in their construction. By 1947 British rule ended in India, but Rawlplug remained a household name for fixing systems.

After all this time Rawlplug is now coming back to India.

In 2005 the Polish Koelner Group acquired Rawlplug. Koelner changed the whole operation of Rawlplug by strengthening and developing the company, with an expansion plan to diversify and to spread into emerging markets.

Rawlplug re-established itself in India in 2011 with its partner - JV-ONE INDIA. Principally it is managed as an independent company - Rawlplug India Pvt Ltd. Its headquarters are in Bangalore and it has two managing directors - Mr Mazen Mallas and Mr Syed Ismail from JVONE INDIA. Rawlplug India Pvt Ltd

re-introduced itself to the Indian market at the 2011 Fastener Fair in Mumbai, and has also held various technical seminars in different parts of the country to remind Indian customers of the potential of Rawlplug’s vast range of products.

“India is emerging as the fastest growing economies in the world and with the entry of Rawlplug at this time, the brand will gain bigger momentum, due to its history and as well its strength, to be the most advanced company in the field of fastener and fixings,” commented Mr Mazen Mallas.

Mr Syed Ismail added: “Rawlplug India plans to establish a team of highly qualified professionals within all metro cities and major business centres in India, to provide the support and solutions for the various construction activities.

Mr Syed Ismail has pledged to “lift Rawlplug India to its highest level with utmost satisfaction to its client needs and also to emerge once again in the Indian market as the ‘guru’ in the field of fixings and fasteners.”

The reasons for choosing Rawlplug include: • A vast range of special anchoring systems to meet the requirements of wide variety of applications.

• Specialisation in each group of products.

• High quality – manufacturing unit in Europe.

• Strong R&D department and technical research.

• Worldwide material availability.

• Cost-effective solutions in response to growing market demands; best production facilities and shortest possible delivery time.

• Marketing and technical support.

• Strong business ethics and codes.

• Generic name - brand awareness. www.rawlplug.in

Many of the great projects commissioned under the British, used Rawlplugs. Some of them include: 1920 - 1937 Khyber Railway Station The Khyber Railway Station project was commissioned in 1920 under the governor general of India at the time.

Rawlplug’s were used for general fixing and electrical fixing.

1912 - 1931 Rashtrapati Bhavan

Located at Raisina hill in New Delhi, India.

Until 1950 it was known as “viceroy’s house” and served as the residence of the viceroy and governor general of India. At present, it is the largest residence of any chief of the state in the world. Extensive use of Rawlplug’s was witnessed in many types of fixation.

Fastener + Fixing Technology

Raising the bar for high temperature applications How well can your fastener assemblies take the heat? Do you worry about high temperatures that can cause failure? Do you wonder if there is a fastener application that works beyond 475ºF (246ºC)?

ND Industries has developed a fastener locking patch which it says eliminates these concerns.

N

D Hi-Temp Patch ® performs in temperatures ranging from -70ºF (-57ºC) to +500ºF (260ºC) and is used on applications in the automotive, construction, medical, electronics, aerospace, and defense industries.

How is patch an improvement upon traditional thread-locking methods?

A patch is a coating applied to a fastener that creates a positive lock, preventing loosening and leakage at the fastening point. One of the more practical benefits of a patch application is that it replaces the need for costly lock washers, cotter pins or castellated nuts. These types of hardware components were the most commonly used methods to prevent fastener slippage before patch technology was available. Patch technology has shown to be more cost effective on larger runs than bottled thread-locking compounds that require application at the point of assembly.

How is ND Hi-Temp Patch better than other patch materials?

Although high temperature patch creates the same kind of lock, with the same resiliency and benefits as a standard nylon patch, it also has the capacity to retain locking reliability at high temperatures. Standard patch may fail to retain functional integrity when exposed to temperatures above 250ºF (121ºC). Most polyester based high temperature patch coatings will not endure temperatures exceeding 400ºF (204ºC). Even Nytemp ®, the high temperature patch produced by Nylok ®, does not retain reliable locking properties beyond 450°F (232ºC). However, ND Industries’ ND Hi-Temp Patch can withstand temperatures as high as 500ºF (260ºC) without compromise to its locking power.

During the patch coating process the fastener to which the patch is being applied is heated to a precise temperature. This heating allows a powdered polymer material to flow into the shape of the fastener thread. During the ND Hi-Temp Patch process the custom formulated polymer material is stabilised to work at extreme high temperatures. It is typically applied 2 to 3 threads back from the fastener end for easier starting of the nut/bolt assembly.

22 Fastener + Fixing Technology • Issue 4 Jan - Mar 2012

The applied coating material fuses to the heated fastener instantly. No curing time is required. Since ND Hi-Temp Patch is not chemically reactive, once the fastener is cooled, it’s ready to use right out of the box. This means that ND Hi-Temp Patch treated fasteners can be immediately fed through automatic feeding equipment, saving precious time in the assembly process. Because the ND Hi-Temp Patch coating process entails no drilling or milling, the fastener to which a patch is applied does not lose any structural strength. ND Hi-Temp Patch coating can be applied to almost any internally or externally threaded metallic fastener, whether large construction bolts or minuscule screws used in portable electronic devices.

Moreover, the nylon-like material used in the ND Hi-Temp Patch coating process is highly chemical resistant, and will not dry, shrink, or lose its integrity even when exposed to corrosive materials such as commercial solvents, alcohol, gasoline, motor oil, caustic soda, jet fuel, anti-freeze, or brake fluid.

The ND Hi-Temp Patch coating, like typical patch, works effectively like a spring or a dam. When a ND Hi-Temp Patch coated fastener is threaded onto a mating part, the patch material is compressed, exerting a constant spring like locking pressure between the fastener and its mate. When the fastener is fully seated, the positive seal created prevents fluid leakage and is resistant to loosening, even when subjected to extreme shock impact and prolonged vibration. This resistance greatly reduces the need to retighten fasteners.

ND Hi-Temp Patch is not only easier and more cost effective than outdated sealing methods, but a fastener treated with ND Hi-Temp Patch is adjustable, removable, and reusable, all while maintaining its locking force under the strains of extreme environments.

ND Industries develops and supplies high quality fastener coating products and services to a wide variety of industries.

K

ee Safety is widely known for its renowned Kee Klamp ® structural fittings for making handrailing, guardrailing and other tubular structures. Alongside this, Kee Safety offers ever growing product ranges of roof top fall protection systems for collective and personal protection.

The company manufactured its first Kee Klamp ® casting in 1936 and has ever since been producing extremely high quality complex products. All Kee Safety products are sold with approvals, test certificates and are supported by an experienced technical team.

Kee Safety has facilities across the world, with offices in the UK (5 offices), France, Germany, Poland, Dubai, Canada, China and 5 offices in the USA. It also has its own export department operating out of the UK, which looks to seek partnerships in areas where Kee Safety doesn’t have its own presence.

BeamClamp® - Pre-engineered clamping system The BeamClamp ® range is a series of clamps that are used in conjunction with structural bolts to provide a solution for securing steel together without the need for traditional on-site methods such as welding or drilling. When all the costs that are required to make a connection are calculated, in the majority situations the clamping system is the most economical as the installation speed and labour costs are vastly reduced.

There are many other benefits such as a guaranteed load, adjustability, no damage to existing steel or coatings, no hot work permits and no debris created from drilling.

These benefits are becoming very important in situations where drilling and welding can create hazards. The clamping system (pictured right) is ideal for the connection of monorail and conveyor systems commonly seen in automotive production.

BoxBolt ® - Blind fastener for steel hollow section The BoxBolt ® range is the blind fixing solution for connecting into hollow sections or where access is restricted to one side only.

This system provides an economical solution to making blind connections when compared with traditional methods such as welding or bolting through. The system eliminates complicated fabrications such as welding internal nuts or providing internal stiffeners to reduce crushing from tightening.

Quality/new product development Kee Safety pride itself on providing a quality product that is compliant to all relevant approvals and legislation specific for the market it will be used in. The BeamClamp ® and BoxBolt ® products are approved by Lloyds Register and DIBt and go through regular external audits from these approval bodies.

fastener + fixing technology

Innovative technology for innovative companies Böllhoff Group has developed the ECOSIT RFID Bin solution which it says optimises the value added chain of industrial companies. The product focuses on the logistics of ‘C-parts’, which have traditionally been relatively expensive to procure. Here Böllhoff explains how the new system is able to offer considerable cost benefits whilst improving the security of supply.

F

rom 100 to 0 and back to 100. We’re not talking about the acceleration and deceleration of a car here, but rather production capacity utilisation trends at many companies over the past two years. Fluctuations in demand have never been as vast and as unpredictable as they are today. This has a huge effect on the security of supply – including for C-parts.

In the current climate it is more important than ever to have a supply system which secures the supply when the output and procurement volume are highly volatile. To help achieve this Böllhoff has managed to cleverly and advantageously integrate RFID technology into customers’ existing supply chains.

automatically read off the RFID tags and transmitted to Böllhoff’s ERP system. This process takes just a few seconds and requires no manual intervention, which means that deliveries can be made much faster and with much greater flexibility than in the past.

One particular advantage of the process is that the existing rack systems and workflows can be retained. Furthermore, it involves no extra work for the customer’s staff. It is simply a matter of replacing the old barcode labels with RFID labels.

One or more collection boxes for the empty containers and an RFID scanner complete this new, innovative supply system solution. As the collection box only holds plastic containers, there is no interference with the radio signals, thus ensuring the reliability of the RFID Bin system. This technology can be easily integrated into the existing infrastructure and can be started up within a few minutes.

Control and transparency

Böllhoff customers receive online access to their ECOSIT system and can view current system information and the data archive history at any time. This ensures 100% transparency.

Moreover, the system also includes online queries and evaluations, a download function, global availability and data security with 128 bit encryption.

All in all, companies with ECOSIT RFID Bin can enjoy considerable cost benefits thanks to short lead times and consumption based delivery schedules whilst reducing administration.

At the same time, this innovative system underlines Böllhoff’s own commitment to consistent customer orientation by optimising processes, reducing costs and reinforcing competitive positions.

Advantages of RFID technology in ECOSIT systems

RFID solutions in supply systems

RFID is currently used in all automatic detection and monitoring systems. In the private sector, vehicle immobilisers, ski lift passes and anti-theft devices in retail are the best-known applications.

At present, barcodes are usually placed on the containers in which the companies store their parts. When required, the barcodes are manually scanned with scanners and the data is sent to the supplier in subsequent steps. The goods are then picked and delivered. The data is recorded and transmitted at set intervals. Unfortunately this means that another container could run down soon after all the empty containers have been scanned.

Böllhoff is one of the first companies in the industry to apply state-of-the-art RFID technology to C-part procurement. The result: deliveries can now be made much more quickly and with greater flexibility. This saves time, keeps costs down and reduces the risk of supply bottlenecks.

The system is simple and reliable, because all the relevant data is saved on the RFID tags of the container labels to ensure prompt delivery. As soon as a container becomes empty, it is placed in a collecting bin positioned beside the rack. The data is

Blind Rivets

A Riveting Experience

Extra grip, extra strength from Orlock

ORLOCK Double locking system OR-BULB Split Tail STELOCK / STEEL-FIX Steel High Strength and Multi-Grip

Ornit Blind Rivets has brought together lightweight, environment friendly aluminium and the double locking Orlock 7.8mm rivet to create a powerful structural fastener.

U-FIX High Versatile Multi-Grip

luminium is one of the lightest commercial metals available, yet its high strength to weight ratio makes it ideal choice for industrial uses. Ornit uses an aluminium alloy with high strength, ideal for manufacturing structural blind rivets. Another advantage of aluminium is the thin layer of aluminium oxide that forms on the surface when exposed to air, making it resistant to corrosion and so increasing Orlock’s overall corrosive resistant properties.

Ornit’s Orlock fasteners are well-known for their double locking system: two sets of gripping grooves locking the mandrel in the rivet body and creating a secure, vibration resistant joint. On set-up, the Orlock forms a large blind side area, spreading the clamp load over a large surface area, making it ideal also for fragile, thin and soft joint materials.

Orlock Alumimium 7.8mm is a powerful fastener with extra grip and extra strength and ideal for aluminium joints.

Orlock 4.8mm & 6.4mm are also available in aluminium in a variety of head types and grip ranges.

Ornit Blind Rivets highlights that is has joined several social media communication platforms, aiming to improve its service by improving customer accessibility on technical and commercial questions. Ornit believes its social media presence will also make the up-to-date information on applications markets and company easily reachable. The company says it will reach out to target markets and customers promoting the “to-be-launched” and existing large range of standard and structural blind rivets. Customers may now access Ornit’s catalogue from Facebook, peruse Ornit’s latest news on Twitter, view Ornit’s product pictures on Picasa and watch Ornit’s promotional media on YouTube. www.ornit.com

Making the connection with Masrivs Rivit Srl is recognised for its innovative approach to supplying fastening systems for metal sheets and the tools for their application.

R

ivit has now presented Masrivs, a blind fastening solution that solves the problem of connection in a wide range of electrical equipment, where grounding must be guaranteed.

Masrivs can replace the traditional usage of bolts, nuts and knurled washers that may not satisfy the safety conditions for grounding.

The technical performance of the Masrivs is ensured by the penetration of the ‘faston’ terminals which, when setting the rivet scratch a painted surface to ensure conductivity.

The Masriv rivets consist of a copper body and a copper steel mandrel. The brass faston has terminals and, depending on which of the various available versions can have one terminal (45° or 90°), two, or four terminals, inclined at 90°. www.rivit.it
