Miniature, Lightweight, Heavy Duty & Extra Heavy Duty Threaded Insert Types with Non-locking and Self-locking Internal Threads

Acme keylocking threaded inserts are used to quickly repair stripped, damaged or worn out threads. Threaded insert products are also used in original equipment where they strengthen threads in soft metal like magnesium or aluminum.

Our threaded inserts are easy to install and remove. No specialty drills, taps or pre-winder tools are required. The keys are driven down into the threads of the surrounding base material, locking the insert in place.
