Dave Newland, NavSim Technology Inc
Vice-President, Research and Development
Your screws are truly a work of art! You really deliver a fine product. I already let our contract manufacturer know to go ahead and recommend you to any of their other clients.
Chad Haas, Haas Technologies
I had finally purchased after about a year of thinking about it and I use them like mad. I am very happy with my registered Rex head screws and wish that I could purchase more sizes and types, which I will eventually do.
Dave Althoff, Jr., Capital University
I can't remember how long ago we bought a bunch of screws, but the number of data projectors that have been stolen from our campus while properly secured with Bryce screws is still 0.

The World's Most Tamper Proof Security Screws, Nuts and Bolts

Bryce Fastener is the leading manufacturer in the world producing the highest-level security screws, security nuts, security bolts and tamper proof fasteners. Governments, military and nuclear facilities depend on Bryce theft proof fasteners to keep the bad guys out. Banks, schools, prisons and high-tech facilities rely on Bryce fasteners and security screws as do solar panel and medical equipment manufacturers, thousands of retail stores and companies who take protection seriously. From theft proof nuts to vandal proof bolts, Bryce offers it all.  And if one of our anti-theft fasteners isn't right for you, our team of designers will develop one to fit your specific needs.

Bryce Security Screws Stop Theft Before It Happens

Unique and almost impenetrable Bryce Key-Rex, Penta-Plus, Penta-Nut and Raptor security fastener systems keep criminals and tampering hands out so theft is nearly impossible. Bryce tamper proof systems stop the crime, while security cameras and alarms simply provide evidence that theft or vandalism has occurred after the fact. When the highest level of security is required, Bryce security screws are the only choice.

Other "tamper resistant" screws and fasteners are mass-produced and bits are readily available at most hardware stores throughout the world. Bryce's proprietary fasteners are different because they are custom made. The Key-Rex is the most theft proof and tamper proof fastener in the world because every customer receives a different "keyway" for their order of security screws or security bolts that no one else has. Each unique "keyway" is licensed to only one client and no other known mass-produced bit will fit any Key Rex fastener. In addition, their specially designed shape and high-torque abilities deflect vice grips and other tools. When top security is essential, Bryce has the solution.
