BaerCoil® wire thread inserts not only ensure a long-lasting and powerful threaded connection in the thread repair, but also enable scrap recovery. The inserts also create load-bearing connections in materials with low shear strength. Thanks to their precision and wear resistance, the BaerCoil® thread inserts hold your screw firmly in place without changing the thread insert. Ideal for repairing stripped or worn threads. wire thread inserts are often used in automotive, electrical, medical, lightweight construction, and aerospace applications.
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 also 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 are sophisticated design elements that ensure optimum power transmission from the bolt to the nut thread. They compensate for pitch and angular errors and thus distribute static and dynamic work loads evenly over all thread turns. This is particularly important in lightweight constructions where the carrier material is to be reduced. BaerCoil® thread inserts make it possible to use smaller and shorter screw connections. Today, they are already an important component in the aerospace and automotive industries.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
