About Threaded Inserts

Choose the right threaded insert for your application and learn how to install it securely.

Mil.-Spec. Key-Locking Threaded Inserts For Soft Metal

These inserts are manufactured and tested to meet or compare to strict standards adopted by the U.S. military. The keys drive into aluminum and other soft metal for a secure hold that won't slip or rotate, even in vibrating vehicle or aerospace parts. These inserts are comparable to Keensert inserts.

To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.

Standard Wall—Stronger than thin-wall inserts, these are your go-to choice for threading most holes.

Extra-Thick Wall—Stronger than standard- and thin-wall inserts, use them to reduce the size of tapped holes or replace threads that have been drilled out.

High-Strength Cadmium-Plated Alloy Steel—These inserts have the strength to stand up to high-pressure applications and a plating that helps screws thread in smoothly.

18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

Air-Powered Key-Locking Threaded Insert Installation Tools

Install key-locking inserts in a flash. Instead of threading and hammering inserts in by hand, these air-powered tools do both steps with the pull of a trigger. Release the trigger and the tool automatically resets, ready for the next insert. They’re compatible with Keensert inserts.
