STYKFIT 7 by Bryce Fastener

Manufacturer Claim

Patented design provides tight tolerance between bit and screw for a “stick-fit”. Screws don’t fall off the bit, even when bearing weight – perfect for assembly applications.

Fast indexing, ease of use and improved installation times are the result. Looking to make gains in productivity and efficiency with a security screw? This is it.

SmartGrip™ tapered design
Low-Profile Head
Custom torque grip via "Raptor Claw"

What We Thought

STYKFIT®7 fasteners are engineered for high-volume, precision-driven applications where both speed and tamper resistance are essential. The patented 7-fin drive system offers a tight, interference fit that enhances torque transfer and reduces cam-out. The SmartGrip™ tapered design ensures the screw adheres securely to the driver bit, facilitating one-handed installation and minimizing dropped screws. While the drive pattern isn't unique per customer, access to driver bits is controlled, providing a moderate level of security. The low-profile head design further deters tampering by resisting gripping tools.

About The Manufacturer

Founded in 1972, Bryce Fastener, Inc., opened its doors as a fastener distributor in Seattle, WA. For the next 20 years, Bryce provided manufacturers, retail stores and other businesses with all types of screws, bolts, and nuts.

By the early 1990s, the more popular types of tamperproof fasteners were no longer being produced by American manufacturers. With the help of WSR Manufacturing, the first prototype of our Key-Rex® drive was developed. This was a clear turning point—Bryce Fastener needed to further develop and perfect security screws, bolts, and nuts.

By re-engineering cold-forging machines, developing new manufacturing techniques and processes, Bryce Fastener has set a new standard, both in security innovation and in the way security fasteners are made. Today, the talented team at Bryce Fastener are true American craftsmen, producing the most secure fasteners in the world.
