An inexpensive threaded insert designed to be an easy method of repairing damaged threads.
Re-Nu-Thread Inserts are used in magnesium, aluminum, cast iron, copper, masonite, plastics. For load bearing threads in any material.
Re-Nu-Thread Inserts will not back out or vibrate loose. A nylon locking element in the external thread automatically locks the insert in place. Bolts and screws can be inserted and removed without insert movement.
The locking element holds the insert securely in place without the need for lock nuts or other devices. We recommend a 90 degree countersink 1/32" larger than the major diameter of the mating thread to prevent damaging the element.
