BaerCoil Wire Thread Inserts BA 4 - 1.0 D (3.6 mm) - free running - 100 pcs.
BaerCoil® thread inserts are made of high-quality materials wire thread inserts. BaerCoil® thread inserts provide a durable and powerful threaded connection and scrap recovery in the thread repair. The inserts also create load-bearing connections in materials with low shear strength. thread inserts are precise and wear-resistant, holding your screw firmly in place without changing the thread insert. Ideal for repairing stripped or worn threads. wire thread inserts are commonly used in automotive, electrical, medical, lightweight construction, and aerospace applications.
The BaerCoil® thread insert is the perfect solution for damaged threads and that at the same time 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 are sophisticated design elements that ensure optimum power transmission from the bolt to the nut thread. They compensate for pitch and angular errors and thus distribute static and dynamic work loads evenly over all thread turns. This is particularly important in lightweight constructions where the carrier material is to be reduced. BaerCoil® thread inserts make it possible to use smaller and shorter screw connections. Today, they are already an important component in the aerospace and automotive industries.
BaerCoil® thread inserts can be shortened, according to the required length, with a side cutter or similar.
