Keylocking Threaded Inserts

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.

Acme threaded inserts are easy to install and remove. No special 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.

Benefits of Acme Threaded Inserts:

  • Solid, one-piece threaded insert construction provides a high degree of pull-out strength
  • Threaded Insert Keys supply a positive mechanical lock against rotation
  • Easy threaded insert installation and removal: Installed with standard drills and taps, No pre-winder tool required
  • No tang to break off

  • Acme threaded inserts come in sizes: Miniature, Lightweight, Heavy Duty and Extra Heavy Duty threaded insert types with Non-locking and Self-locking internal threads
