BaerCoil® wire thread inserts provide a long-lasting, powerful connection and scrap recovery in the thread repair. They also create load-bearing connections in materials with low shear strength. Precise and wear-resistant, the inserts hold your screw firmly in place without deforming the thread insert. Ideal for repairing damaged or worn threads. wire thread inserts are often used in areas such as automotive, electrical engineering, medical technology or lightweight construction as well as in aerospace.
The BaerCoil® thread insert is the perfect solution for damaged threads. With the use of 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. Due to their flexibility, they can compensate for pitch and angle errors and thus guarantee optimum force transmission. BaerCoil® thread inserts are already important components in the aerospace and automotive industries and help to reduce carrier material and use smaller, shorter bolted joints.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
