Key-Rex® Set Screw

TAMPERPROOF(Minimums Apply)

Key-Rex® is the most secure, tamper-proof screw technology on the market. It's not available in any stores. And now you can have the most secure set screw in the world.

The market has caught up to common tamper-proof screws. New shapes are continually coming to market only to be followed by easy-to-find drivers that match them.

Don't take chances, get your own set screw with your Key-Rex® private keyway profile. Only you will have the driver bit to match. It doesn't get more secure than that.

Available in sizes 2/56-1/2 (length cannot exceed the diameter).
Stainless Steel, Alloy, and Coated.

Unique to each customer

Every set of Key-Rex® screws and bolts are custom "keyed" for a specific customer. And only that customer has the bit to fit their custom set of screws.

This unique keyway shape is created using an encryption process that builds the profile shape out of millions of variables and defines a one-of-a-kind keyway design. Customers pay for a one-time key code tool and licensing agreement.

"Try to remove one without the driver bit. Then you'll know."- James Graw, National Laboratories, Providence R.I.

“Key-Rex® isn’t for everyone.”

Key-Rex has been a very popular product, but it's not an off-the-shelf solution. That's why there is a minimum order required. The customized nature and keyway lends itself to extremely secure, high-value applications.
