BaerCoil Wire Thread Inserts M 4 x 0.7 - 1.5 D (6 mm) - free running - AISI 316 - 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. Today, they are already an important component in aviation and vehicle construction. They save weight and allow the use of smaller and shorter bolted connections.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
