SPECIALTY FASTENERS AND COMPONENT SUPPLIERS IN ONTARIO What are specialty fasteners? Specialty fasteners are the unique varieties of fasteners that are manufactured for a specific industry, job or material. In comparison to general-purpose fasteners, specialty fasteners have limited or particular applications. Applications of specialty fasteners Specialty fasteners are used in the aerospace industry and other industries. Factors to consider when choosing specialty fasteners in Ontario Many fasteners are designed for special functions or material requirements. Here are some of the design factors to consider when selecting specialty fasteners – 1. Communication: It is essential to provide precise inputs to your specialty fastener supplier about the specifications and dimensions of the fasteners. This will guarantee sufficient lead time to design the fastener, conduct tests and make necessary alterations. 2. Under-engineering: The purchase of specialty fasteners should not be made solely on a price basis. The fastener may be improper for a particular application or too frail for a job. Do not specify single-threaded fasteners where multiple threads are required. Never use standard fasteners for an application that needs specialty fasteners. 3. Over-engineering: Beware of over-engineering when it comes to specialty fasteners. Do not purchase metal that is too heavy for an application, critical tolerances where they are not required or large nut and bolt combinations. 4. Finish: Choose finish after the supplier understands your specialty fastener needs. Ensure that the Finish hardness is based on the application. 5. Material: It is important to match the grade of steel to the application. Take into account the gauge thickness. 6. Fastener functions: Specify to the fastener supplier what the fastener will do when ordering. Consider the fastener limitations. 7. Servicing: Before ordering, understand if the fastener will be removed. If so, determine how often it will be removed and if special tools are required and inform the supplier accordingly. 8. Assembly techniques: Be sure the specific fastener you are ordering is compatible with the existing automatic assembly equipment. Never compromise the fastener reliability for assembly speed.
