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.

Kinmar Removable by Hafren Security Fasteners
The Kinmar® Removable fastener offers a flexible tamper-resistant option for low-risk applications, but its design leaves critical vulnerabilities. The flat top makes it easier to grip with locking pliers or attack with rotary tools, and although the manufacturer claims the driver socket is restricted, it can be found online for around $170—undermining the intended access control. Its use is best limited to low-value or controlled environments where convenience outweighs high security.
