BaerCoil® thread inserts are the perfect solution for your thread repair needs! These inserts provide a long lasting and powerful thread connection and scrap recovery.
The BaerCoil® thread insert is the perfect solution for damaged threads. STI thread (Insert thread) is cut and the BaerCoil® insert is screwed in. The thread produced is significantly stronger than the original thread.
Our thread inserts ensure that both static and dynamic work loads are distributed in a balanced way to the individual thread turns. The flexibility of the thread inserts also compensates for any pitch and angle errors, so that optimum force transmission from the bolt to the nut thread is achieved. Particularly in lightweight constructions, BaerCoil® thread inserts helps to reduce the carrier material and to use smaller or shorter screw connections. Today, they are already an important component in aviation and vehicle construction. They significantly save material and contribute to the conservation of resources.
BaerCoil® thread inserts can be shortened according to the required length with a side cutter or similar.
