BaerCoil Wire Thread Inserts UNC 1/2 x 13 - 2.5 D (31.75 mm) - free running - 100 pcs.
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.
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.
BaerCoil® thread inserts can be shortened to the required length with a side cutter or similar.
