$100 minimum purchase required.
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.
“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 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.

Fast indexing, ease of use and improved installation times are the result. Looking to make gains in productivity and efficiency with a security screw? This is it.See More
