Strongest bolted connection BAER, based in Heddesheim, Germany, says that its new BaerCoil System is strong, wear-resistant and offers enormous saving potential for material, weight and costs.

he BaerCoil System’s construction provides new possibilities for commercial usage and for the strain capacity of screw joints. Engineers from nearly all mechanical engineering fields are searching for building components that have a greater strain capacity and for ways of reducing both weight and costs. Bolted connections must also fulfil these requirements. Thus, they have continuously been the focus of innovation. BAER explains that its BaerCoil wire thread inserts, which are turned into a formed parent thread, achieve exceptional pull-out strength* and wear resistance values. There are two reasons for this:
BaerCoil
®
• • • •
highest tensile strength minimize weight and space minimize costs strengthening threads for new construction options • thread repair
BaerFix
®
• minimize space and weight of parent material • thread reinforcement • very high tensile strength • high connection with workpiece • thread restoration
strongest bolt connection for construction: saves material, weight and costs

• The thread is formed and not cut. Specialised BaerCoil forming taps, which form and plasticise the material, are used for this purpose. The parent thread material is compressed to make it denser. Result: The thread into which the BaerCoil wire thread insert is turned has a significantly higher strain capacity. The process of thread forming is quicker and produces a better surface than thread cutting. Additionally there are no chips, and the thread forming tap has a longer life time. • The BaerCoil wire thread insert ensures an optimal distribution of pull-out load for the thread turns across the entire thread length. By comparison the first two threads of a normal screw joint often carry over 70% of the load. An even distribution across the thread insert greatly increases tensile strength. The longer the thread insert, the greater the strain capacity is compared to a normal thread. “The BaerCoil System’s combination of thread forming and wire thread insert make modern dimensions possible for construction, development and improvement of previous building components. Customers, after performing internal tests, are already taking advantage of the system and have integrated it into their production process.” *Cryogenic Materialtests CryoMaK within the Institute for Technical Physics at the Institute of Technology in Karlsruhe – KIT –conducted the pull-out strength tests. www.baercoil.com
