High Quality Threaded Wire Insert

Wire thread insert is a new type of internal thread fastener, suitable for threaded connections. 

It is screwed in and fastened in the threaded hole of one of the connected parts to form a standard internal thread, and then a bolt (or screw) is screwed into it. 

Also known as threaded wire insert, it is abbreviated as wire insert. It is precisely processed from high-strength, high-precision, and smooth-surfaced cold-rolled rhombic stainless steel wire to form a spring-like concentric body of internal and external threads, mainly used to enhance and protect the internal threads of low-strength materials. 

Its principle is to form an elastic connection between the screw and the internal thread of the base, eliminating thread manufacturing errors and improving connection strength. Internal Thread Fastener are embedded in the threaded holes of low-strength engineering materials such as aluminum, magnesium alloys, cast iron, fiberglass-reinforced plastics, and plastics, and can form high-precision internal threads that meet international standards. It has the functions of high connection strength, earthquake resistance, impact resistance and wear resistance, and can disperse stress to protect the base thread, greatly extending the service life of the base, and is widely used in electronic applications.
