Security Screws - Different by Design

Our products may look like the typical tamper-proof security screw, but they are far different. Our security screws have been designed around the faults found in the security screw industry. The main fault begins with the easy access at retail to security screw bit tips. Millions of security screw drivers have been sold over the years, legally impacting the claims made. Once, the industry advertised their screws were tamper-proof. Later, they became tamper resistant screws or vandal resistant. Finally, the industry leaders could only claim their fasteners were intended to be security screws and nuts. Besides tamperproof bits sold retail, there also emerged many other removal tools such as vice grips, channel locks, and easy outs. Typical security screws today provide hardly any security and at best mild tamper resistance. Knowing this, we decided some 15 years ago to design something different. We reengineered the security screw with lock features that made them more secure than any fastener has ever been. Though they look similar, they are far different.

The Bryce collection of custom, theft proof security screws.

We even trademarked the name Keyed-lok®, for that's what our security screws are: keyed locks. 


We are different by design. We also design differently. Our security fasteners work differently than any other security screw and require that standard screw and nut specifications be changed. Though we follow some guidelines, we design your fastener, not an outside engineer. We have the expertise to figure out what fastener will work best for you. We guarantee they will work. In this age of customer specifications, our concept is an exception. After spending years experimenting and changing the way security fasteners are made, we know what works. We'll take full responsibility for the security designs we supply as part of our guarantee. They will be different, but work the best for your application.
