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.

The Intimidator by McGard
The Intimidator offers solid tamper resistance with proprietary key patterns and regional key code tracking. However, the exposed head shape makes it easier to grip with common tools like locking pliers, which may be a concern in higher-risk environments. While the drive pattern is proprietary, it isn’t unique per customer. It’s still a practical choice for shared-access applications like municipal or utility use—but not the strongest option for physical tamper resistance.
