How to Install Key-Locking Inserts

Lubricated Stainless Steel
Helical Inserts without Prong

A dry film keeps the screw from sticking or binding in these inserts during installation.

Key-Locking Inserts for Soft Metal

18-8 Stainless Steel Key-Locking Inserts

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

Mil. Spec. Stainless Steel Key-Locking Inserts

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.

Aligning Key-Locking Inserts

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.

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.

Key-Locking Inserts with Installation Tool

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

316 Stainless Steel Tee Nut Inserts for Wood

The most corrosion resistant tee nut inserts we offer, these inserts stand up to chemicals and salt water.

Thread-Shielding Tee Nut Inserts

Create strong threads in wood and plastic that won’t get clogged with paint or debris. These tee nut inserts have a protective plug on bottom to block out substances during finishing processes.

18-8 Stainless Steel Split-Resistant
Tee Nut Inserts for Hardwood

With only three prongs—fewer than our standard tee nut inserts—these inserts are less likely to split hardwood. They’re made of 18-8 stainless steel, so they stand up to mild chemicals and water better than steel inserts.
