Tri-Wing
This fastener is widely available and lacks meaningful tool control or tamper resistance. While often marketed as a "security screw," it does not meet our standards for the security classification. It may deter casual tampering but offers very little protection against intentional removal.

Ultra-Lok II by Loss Prevention Fasteners
The Ultra-Lok II® features a proprietary keyway with a robust center stud, adding strong protection against tampering with standard tools. Tools are restricted and require authorization to purchase, increasing control—but not eliminating the possibility of eventual tool access. The button head design also limits grip area for pliers, especially when paired with proper torque. Minimum order quantities may limit use for small projects, but this fastener offers solid mid-tier security where distribution control is important.
