STYKFIT 7 by Bryce Fastener
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.
