25 Years of Satisfied Customers

Unique geometry and controlled availability make for the perfect fastener when off-the-shelf security isn’t enough.

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.

Customer Testimonial

65,000 Screws.
Zero Theft.

“I've bought thousands of Bryce security screws for our pull-box products that secure buried copper wiring. In over a decade we haven't had a single reported breach. None. I attribute that to the fact that Bryce fasteners aren't sold on the open retail market and they're engineered to repel every knock-off tool out there.”

Penta-Nut™

Turn any bolt into a lock.

Penta-Nut is the largest diameter security nut available, and with the added Raptor™ Security Head, no washer is needed.

And in an application where bolt threads are exposed, combine Penta-Plus™ Bolt with Penta-Nut for the highest level of security.
