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

High-Strength A286 Stainless
Steel Key-Locking Inserts

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.

Closed-End Key-Locking Inserts

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

Screw-Locking Key-Locking Inserts

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.

Alloy Steel Thin-Wall Swage-Locking Inserts

Alloy Steel Thin-Wall Swage-Locking Inserts

Add or repair threads near the edges and corners of soft metal surfaces—these inserts have thinner walls than any of our key-locking and thread-locking inserts. Made of alloy steel, they’re stronger than our 17-4 PH stainless steel inserts.

17-4 PH Stainless Steel
Thin-Wall Swage-Locking Inserts

17-4 PH Stainless Steel Thin-Wall Swage-Locking Inserts

Position strong, corrosion-resistant threads close to the edges of soft metal surfaces. These inserts have thinner walls than our key-locking and thread-locking inserts, so they don’t need as much space around them.

Mil. Spec. Rivet-Mount Nuts

Mil. Spec. Rivet-Mount Nuts

Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped.
