What is a Helicoil Thread Insert?

A helicoil thread insert is a coiled-wire type of thread repair insert used to create internal screw threads to accommodate standard-sized fasteners.  This product is a helically  wire that has a cross-section that allows the external portion of the wire to screw into the receiving threads in the housing during installation.

The spacing between the coils of the insert form new conventional threads on the inner side of the wire.  The coils of the insert are compressed during installation as the insert is threaded into position.  Like a coiled spring, the compressed windings of the installed insert attempt to expand against the walls of the threaded housing. The resulting tension between the insert and the walls of the housing helps to retain the insert and keep it from unthreading.

This thread repair kit contains everything you will need to repair a female thread in steel, cast iron or aluminium.  The sprung insert coils will create a stronger thread than the original metal.  This Helicoil Thread Repair kit os from the Silverline Tool range and offers high quality at a competitive price.
