Wire Thread Auto Repair Inserts

Wire Thread Auto Repair Inserts

Free Running Wire Thread Insert coils are manufactured by forming the stainless steel wire into a diamond shape and then winding it into a spring. Before being installed, the Stainless Steel Wire Thread Repair Insert diameters of these stong internal threads are larger than the tapped hole. During installation, the insert diameter of the helical coil insert is reduced, allowing the insert to thread into the hole. Once properly installed, the radial pressure of the released insert holds the insert firmly in place.
