Helicoil inserts are very common in CNC machining. In the machining of mechanical parts, helicoil insert is the thread sleeve, it is after we tap the thread, and then install a thread sleeve.

Why do we need helicoil inserts?

Helicoil insert increases connection strength + wear resistance + rust resistance + anti-loosening + seismic resistance = prolonged thread life. Because the thread belongs to the assembly position, it is often tightened and loosened, and after long-term operation, the thread will be damaged, resulting in the phenomenon of slipping teeth and screw threads. helicoil insert is made of high quality stainless steel wire and the screw sleeve diameter is larger than the screw hole, so the helicoil insert has a larger contact surface and is therefore stronger than the original thread. Many designers will take this into account when designing products, and mark which threads require helicoil insert on the drawings, in order to extend the service life of the threads and thus extend the service life of the entire product.
