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.

Low-Profile Head Deters Tampering

The obvious tactic to defeat a bolt or screw is to simply “grip it” and remove it. The sloped, low-profile Bryce button head shape repels tampering tools. Locking pliers simply can’t get a hold of the sidewall like other screws.

Meets all IFI specifications. Order with confidence.

20% More Torque with Raptor™ Claws

Right out of the box, every Bryce security fastener boasts higher torque capability than competitor fasteners. 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® 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.
