BaerCoil Wire Thread Inserts M 4 x 0.7 - 1.0 D (4 mm) - free running - Bronze - 100 pcs.
BaerCoil® thread inserts are the best solution for your thread repair! With them you can create long-lasting and powerful threaded connections. The 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.
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).
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 power 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.
