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. Standard security fasteners are the Achilles’ heel of your security system. There is nothing standard about Bryce’s services.

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
  • Investor-Owned Utility Services
  • And Other Utility Services and Infrastructure Investments.

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 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 am a security manager at a large public utility company in the Midwest. After several breaches over a short period of time, hardening our security became my number one priority. So I asked around and Bryce was highly recommended by a number of people. We ended up replacing every perimeter screw with the Key-Rex over three years ago. Since then, we've had zero break-ins. And we can see that they've tried. We are big believers in the effectiveness of Key-Rex bolts.
