These inserts are made to stringent military specifications.

The strongest key-locking inserts we offer, these inserts are made to stringent military specifications.

These inserts come with an installation tool. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts.

A distorted thread grips the screw to resist loosening.

Assortments include various sizes of helical inserts and a tap, a drill bit, and an installation tool for each thread size.

Made of 18-8 stainless steel, these inserts have better corrosion resistance than black-phosphate steel.

About twice as strong as aluminum rivet nuts, these low-profile rivet nuts have a cadmium or tin-zinc plating for corrosion resistance.

Stainless steel nuts have excellent corrosion resistance in most environments.

About half the strength of medium-strength steel coupling nuts, these metric nuts are for light duty fastening applications.

Place the tip of these tools into an insert and strike them with a hammer to drive the keys into the material. They’re compatible with Keensert® inserts.

Screw an insert onto these tools and drive them a quarter to half-turn below the material's surface. They're compatible with helical inserts that have a prong.

Place the tip of these tools into an insert and strike a light blow to the tool’s head. Then turn the tools counterclockwise with pressure to extract the insert.
