Recoil Thread Repair Insert

Recoil Thread Repair Insert

Tangless Thread Insert is designed to offer the same reliable thread strengthening whilst minimizing the risk of losing a 'tang' associated with tanged inserts. Generally, Wire Thread Insert use a small, piece of material at the bottom of the insert to provide a catching point for the installation tooling, making installation possible. The tang is broken off and removed after installation.

Tangless Free Running Insert, however, can be installed without the use of a tang using specialised tooling and an installation notch on the bottom coil of the insert. The absence of a tang eliminates the risk of the metal tang falling into safety critical applications such as engines or electronic equipment.
