BaerCoil® thread inserts are the perfect solution for your thread repair needs! These inserts provide a durable and powerful thread connection and scrap recovery.
The BaerCoil® thread insert is the perfect solution for damaged threads - with the same nominal diameter! For thread repair with wire thread inserts, the thread is drilled out and a new STI thread (screw thread insert) for the wire thread insert is cut. This thread is often also called STI thread (STI=Screw Thread Insert).
Our thread inserts ensure that both static and dynamic work loads are distributed in a balanced manner over the individual thread turns. The flexibility of the thread inserts also compensates for any pitch and angular 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.
