Exclusive-to-you design that’s engineered for zero-theft.
100% made-to-order, right here in Gilbert, Arizona.
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.
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.
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.
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.
