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 an indispensable component in aviation and vehicle construction. They ensure that both static and dynamic work loads are distributed in a balanced manner over the individual thread turns. Also, the flexibility of the thread inserts compensates for any pitch and angular errors, so that optimum power transmission from the bolt to the nut thread is achieved. Particularly in lightweight constructions, BaerCoil® thread inserts helps to reduce the carrier material and to use smaller or shorter screw connections. Thanks to their versatility and reliability, BaerCoil® thread inserts are now an indispensable component in many industries.
BaerCoil thread inserts can be shortened to the required length with a side cutter or similar.
