For thread repair with wire thread inserts, the thread is drilled out and a new STI thread (screw thread insert) is cut for the wire- thread insert. Often this thread is also called STI thread (STI=Screw Thread Insert).

BaerCoil® thread inserts ensure optimum power transmission from the bolt to the nut thread. Due to the flexibility of the thread inserts, any pitch and angle errors are compensated for, so that the loads are distributed evenly over the individual thread turns. BaerCoil® thread inserts are ideal for lightweight constructions, as they reduce the carrier material and enable smaller or shorter screw connections. Today, they are already an important component in aviation and vehicle construction.

BaerCoil® thread inserts can be shortened according to the required length with a side cutter or similar.
