BaerCoil Wire Thread Inserts UNC No. 4 x 40 - 1.5 D (4.27 mm) - free running - 10 pcs.
BaerCoil® wire thread inserts provide a durable and powerful threaded connection in the thread repair. The inserts also create load-bearing connections in materials with low shear strength and are precise and wear-resistant. wire thread inserts are frequently used in automotive, electrical engineering, medical technology, lightweight construction and aerospace. BaerCoil® wire thread inserts are the perfect solution for a long-lasting, powerful threaded 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 frequently used in automotive, electrical engineering, medical technology, lightweight constructions as well as in aerospace.
The BaerCoil® thread insert is the perfect solution for damaged threads. STI thread (screw thread insert) is cut and the BaerCoil® insert is screwed in. The thread produced is significantly stronger 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 evenly over the individual threads. 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 help 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.
