What is a Wire Thread Insert?

A wire thread insert, made by stainless steel, is a spring-shaped metal coil that can be inserted into a pre-tapped hole to form an new thread or to create a stronger female thread.

What do Wire Thread Inserts do?

Wire thread inserts are typically two applications:

1. To repair a demaged thread

2. To create a stronger thread in soft materials such as Aluminium

They are also sold in the form of a thread repair kit along with an installation tool, break tool, twist drill and screw tap providing an all-in-one repair solution which recreates the thread to accept the original bolt. These tend to be very popular for thread repairs in the automotive aftermarket or machinery and avoid costly replacement of components .

Stainless steel GSR thread inserts guarantee a very good corrosion and heat resistance. The cross section is rhombic. The wire is coiled into an elastic spring. There is a tappet at the lower end. While screwing in the thread insert, the spring is slightly tensed and holds the insert in the internal thread.

The threaded set creates a standard high precision internal thread that is superior in all aspects to that created by tapping directly with a tap. Initially designed for use in the automotive and aerospace industries, it is primarily used to repair dead threads and to increase the strength of standard threads. The thread sheath is mainly made of a diamond-shaped stainless steel material wound in a similar way to a spring, and is also known as a wire thread sheath.
