KEY-REX® Tamper Proof Security Screws

Engineered for Security in Every Way

Feature for feature, there is simply no other fastener that can beat the security offered by KEY-REX®.

Fingerprint Key Code™

Similar to your own unique fingerprint. Look carefully — the keyway shape is unique to each customer. Each drive is designed so only that customer can remove their perfectly matched fastener.

Theft Resistant and Tamper Proof Screws

Low-Profile Head Deters Tampering

We've spent decades studying the ways criminals breach security screws and and developing unique security features to keep thieves out. The result is the impenetrable KEY-REX®. There are a wide range of tactics used to defeat standard security screws, like a screwdriver and Dremel tool, or gripping and removing it. The sloped, low-profile design of the Bryce button head repels all types of screwdrivers and special tools. Locking pliers simply can’t get a hold of the sidewall, unlike others. Additionally, the high torque capabilities of the KEY-REX® lock it down on installation, making it nearly impossible for vandals to unscrew without the custom security bit.

Meets all IFI specifications. Order with confidence.

Security Screws With 20% More Torque

20% More Torque with Raptor™ Claws

Right out of the box, every Bryce product boasts higher torque capability than all of our competitors. But it gets better. Add Raptor™ and achieve even more torque — 20% more! Specially designed Raptor™ “claw” serrations on the under side of the head cut and dig into the metal substructure surface, effectively creating a “lock”, resulting in more security and more confidence.

KEY-REX® Security Nuts

KEY-REX® Nut

The most secure nut anywhere.

We created a security nut with many of the same innovative security features as the KEY-REX® Bolts and Screws. Engineered for zero-theft, every set of KEY-REX® Nuts are custom “keyed” for the client and only the client has the sockets to fit.

And in an application where bolt threads are exposed, combine KEY-REX® Bolt with KEY-REX® Nut for the highest level of security.
