PENTA-PLUS by Bryce Fastener
Penta-Plus™ screws offer a robust tamper-resistant solution with a proprietary pentagon drive designed to resist standard tamper-resistant bits. The low-profile button head design deters gripping tools like locking pliers, and the optional Raptor™ Claw feature enhances torque resistance by embedding into the substrate. While the drive pattern is proprietary and bits are controlled by Bryce Fastener, the lack of unique keyways per customer may limit their suitability for applications requiring the highest level of security.

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.
