Acme Industrial Company’s key locking threaded inserts are available in a number of boxed kits. Each kit is designed to provide storage and easy access to a variety of insert sizes, making them especially useful for maintenance and thread repair use.

Each assortment kit contains a selection of inserts, instructions and proper installation tools. Kits for thin wall and heavy duty threaded inserts are available, with either coarse or fine threads, in either carbon steel or stainless steel. Metric and inch versions are available.

In addition to being used to quickly repair stripped, damaged or worn out threads, key locking threaded inserts are employed extensively in new equipment where exceptional pull-out and torque-out strength is needed. Individual (non-kitted) threaded inserts are available in either industrial or MS/NAS insert styles.

The threaded insert’s keys are driven down into the threads of the surrounding base material, locking the insert into place and providing a secure mechanical lock against rotation, the company says.
