Made of 18-8 stainless steel, these inserts have good corrosion resistance.

These inserts are made to stringent military specifications.

The strongest and most corrosion-resistant stainless steel key-locking inserts we offer. Made of A286 stainless steel, these inserts stand up to salt water, harsh chemicals, and even high temperatures.

Protect threads from debris and leaks—these inserts have a closed end as a barrier.

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

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.
