Security Screws for Critical Infrastructure

The Weakest Link in Critical Infrastructure

A LOCK SECURES ONLY ONE THING. When they can't get through the lock, they go for the screws. But Bryce engineered a lock in every screw — and only you have the key to access it. They're perfect for protecting utility pull box lids from copper wire theft. Stop the easy access and you stop theft. Standard security fasteners are the Achilles’ heel of your security system.

The Bolt that Secures Prisons, Military Bases, Nuclear Energy Plants, Aerospace...

We’re in the business of turning potential threats into non-issues — even for the most sensitive customers. Bryce Fastener’s services ensure that every nut, bolt, and screw in your arsenal is a line of defense against unauthorized access, not a point of failure.

We designed the Key-Rex to deter physical threats against critical infrastructure. Increase your confidence in securing the following:

  • Power Plants
  • Power Grids
  • Water Utilities
  • Solar Utility Services
  • Electric Utility Services
  • Nuclear Energy Utilities
  • Renewable Energy Infrastructure
  • Hydro-Electric Power Utilities
  • Alternative Energy Utilities
  • Municipal Utility Service Access Points

Security Screws for Public Utilities

Low-Profile Head Deters Tampering

The most common tactic to defeat a bolt or screw and gain access to critical infrastructure 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.

Customer Testimonial

It's amazing how much better I feel.

I work in the Traffic Engineering sector for a Public Works dept in California. We began using 3/8-16 Key-Rex bolts to secure all our pull box lids throughout the city. When the price of copper goes up, our pull box lids become an easy target. Since the installation of Key-Rex bolts, our lids haven't been tampered with. Hoping to keep the costs of maintenance and repairs down for Vacaville.
