Self-Drill Security Fasteners

The best self-drilling screw on the market

Installer's Dream

Bryce Fastener has improved the design and drive of Self-Drilling(TEK®) fasteners to give you a superior high performing security screw. No wobbles, fast driving, and exclusive-to-you-security. Every installers dream!

We make Self-Drill security screws in all our drives, but recommend Key-Rex®, STYKFIT®7, and STYKFIT®6 (New and Improved TORX®) for the best no-wobble, fast driving, stick-fit feature. The harder you push, the straighter the security screw drives. Straight driving keeps the self-drill point in one place, facilitating accuracy. It also eliminates the “walk scar,” which occurs if the security fastener moves off point. Since most Tek security screw applications are horizontal, this is imperative.

In contrast, the wobbly Tam 6-Lobe™, will not drive straight which lengthens installation times. If you need a Tam 6-Lobe™ drive, our STYKFIT®6 is a great replacement.   

Bryce Fastener’s self-drill security screws work well in fencing, prisons/jails, government metal buildings, solar panels, and robotic applications. When paired with Raptor™ Security Heads, the holding power is increased.

Made in 1022 Alloy Steel or 410 SS.

Tek screws stick so well they can hold up a 5-lb weight.

Bryce Fastener Fixes the Wobbly Fit Problem

A contractor we had hired was using Philips drill-point screws (the kind made inexpensively overseas) in steel studs to frame a new addition to our warehouse. Although Philips is not a security screw, it wobbles just like a Tam 6-lobe™ (aka TORX®). Unfortunately, these wobbly Phillips screws would not drill into flexible steel studs without squirting “off line”. He was frustrated. What should have been a 4-hour job lasted 7 hours. Had he used Bryce Fastener’s security Tek screws, his experience would’ve been different.

Our security fasteners are made with a patented taper which holds strongly onto the security bit. This makes them a one-handed installation fastener, allowing the other hand to hold an assembly piece straight. 3 hours of labor and frustration could’ve been saved.
