A black-phosphate finish provides mild corrosion resistance.

These assortments include various sizes of thread-locking inserts.

Adhesive on both the internal and external threads keeps these inserts in place and holds screws tight.

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

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

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

Forming the strongest hold of any of our threaded inserts, these inserts have a distorted internal thread to lock screws into place and keys that drive into surrounding material to prevent slipping and rotating.

Tap the thread size you need into the solid body of these blanks. Made of steel, they’re stronger than stainless steel insert blanks.
