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.
