BaerCoil® thread inserts are the perfect solution for damaged threads. They are drilled out and a new STI thread (screw thread insert) is cut for the wire- thread insert. This thread is often also called STI thread (STI=Screw Thread Insert). Then the BaerCoil® thread insert is screwed into the old thread and thus the workpieces are screwed on again. With BaerCoil® thread inserts, the thread produced is significantly more stable than the original thread.

Our thread inserts ensure that both static and dynamic work loads are distributed in a balanced manner over the individual thread turns. Also, the flexibility of the thread inserts 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 help 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.
