BaerCoil® wire thread inserts are the perfect solution for a long-lasting, powerful thread connection and scrap recovery. They also create load-bearing connections in materials with low shear strength and are precise and wear-resistant. wire thread inserts are often used in automotive, electrical engineering, medical technology, lightweight construction and aerospace.
The BaerCoil® thread insert is the perfect solution for damaged threads. 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.
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. Especially 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.
