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.
