"I couldn't stop the theft"

After being plagued with theft, I ordered Penta Plus hardware from you. It's been a little over 5 years now, and needless to say, my products have not been tampered with nor have any components been stolen. I have to attribute that to your incredibly secure fasteners.- Grant Johnson, Emagination Engineering

Tamper Proof Screws, Nuts & Bolts

All tamper proof screws are not created equal. In fact, except for Bryce fasteners, most so-called “tamper proof screws” aren’t tamper proof at all. Anyone can buy drivers to the screws most people think of as tamper proof. There are even common drivers to remove those so-called “one-way screws”. So what is your alternative? Truly unique tamper proof screws made by Bryce Fastener.

 Bryce is a U.S. custom screw manufacturer located in Phoenix, Arizona. The vandal proof security screws, tamper proof bolts, tamper resistant screws, security nuts and other security fasteners Bryce manufactures are simply the finest in the world.
