BaerCoil® thread inserts are the best solution for all your repair needs! With them you can create long-lasting and powerful connections. These inserts also ensure that you have no waste and recycle everything. The inserts are precise and wear resistant - your screw will stay firmly in place without the thread insert slipping.
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 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.
BaerCoil® thread inserts ensure optimum power transmission from the bolt to the nut thread - even in lightweight constructions. Due to their flexibility, they can compensate for pitch and angle errors and thus guarantee optimum force transmission. BaerCoil® thread inserts are already important components in the aerospace and automotive industries and help to reduce carrier material and use smaller, shorter bolted joints.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
