A black-phosphate finish provides mild corrosion resistance.

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

Install threads that align with off-center parts. These inserts have floating threads that account for misalignment, allowing you to insert screws at a slight angle as you fasten two parts together.

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

Tap the thread size you need into the solid body of these blanks. Made of 18-8 stainless steel, they resist corrosion from mild chemicals and water.

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.
