Avsafe by Loss Prevention Fasteners
Avsafe® fasteners feature a low-profile, oval head designed to blend in and discourage tampering. Their lack of key-way eliminates common tool engagement points, making them ideal for hygienic or static-sensitive environments. While removal tools are restricted, the absence of user-specific keyways makes them unsuitable for high-security or high-value applications. Avsafe is best where subtle security and cleanliness matter more than physical resistance.

Shear Bolts by Hafren Security Fasteners
The Shear Bolt uses a breakaway hex head that snaps off at a calibrated torque, leaving behind a smooth, ungrippable surface. It's a simple and effective design for creating permanent installations. Once installed, removal typically requires drilling or destructive force. However, the initial install is limited by access to torque tools, and over-tightening or under-tightening can reduce performance.
