BaerCoil® wire thread inserts are the perfect solution for a durable, powerful threaded connection and With the BaerCoil® wire thread inserts you create perfect, durable and powerful threaded connections. At the same time, the use of wire thread inserts allows for scrap recovery and load-bearing connections in materials with low shear strength. Therefore, wire thread inserts is often used in automotive, electrical engineering, medical technology, lightweight construction and aerospace.
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.
