20Pcs Wire Thread Inserts M12 X 1.75 X 1.5D Metric Helical Threaded Sleeve

Metric thread insert is made of 304H stainless steel, which is highly hard, has good corrosion, rust, and oxidation resistance, effectively avoiding thread damage and allowing for long-term use. 304H stainless steel is an austenitic stainless steel with a higher carbon content. It has better high temperature strength and oxidation resistance than ordinary 304 stainless steel. The thread repair kit has a certain elasticity and uniform load, which can make the load on the thread more uniform and eliminate the pitch deviation between the screw and the screw hole. The thread is deep and clear, not easy to slip, not easy to fall off, and not deformed, which greatly improves the strength of the threaded connection and extends the service life of the equipment. Threaded sleeve is widely used in mechanical equipment and engineering machinery. It is the first choice for thread repair and overhaul in aviation, automobiles, steam turbines, electronic communications, computers, lamps, molds, radiators, and semiconductor equipment. The locking wire screw insert can easily lock the screw in the threaded hole. Before use, make sure the screw insert matches the threaded hole and do not install it too tight or too loose; avoid over-tightening the screw insert during use to avoid damaging or loosening the thread.
