Key-Locking Inserts

0 products

Key-locking inserts are designed to secure into threaded holes, offering renewed female threads for fastener engagement. These inserts are screwed into the desired surface, after which the built-in keys are firmly positioned using an installation tool and hammer. This action locks the keys in place, ensuring the insert remains stationary and prevents unintended rotation or loosening. Ideal for restoring compromised threads and enhancing thread durability.
