BaerCoil® wire thread inserts provide a long-lasting and powerful connection in the thread repair. The inserts also create load-bearing connections in materials with low shear strength. thread inserts are precise and wear-resistant and hold your screw firmly in place without changing the thread insert. Ideal for repairing stripped or worn threads, wire thread inserts is commonly found in automotive, electrical, medical, lightweight construction and aerospace applications.
The BaerCoil® thread insert is the perfect solution for damaged threads and that 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) is cut for the wire thread insert. This thread is often 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 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 according to the required length with a side cutter or similar.
