Security Screws

Tamper proof, or tamper-resistant screws provide an added level of protection against vandalism, theft or other tampering threats with a drive design that prevents removal with ordinary screw drivers. Security screws are available in sheet metal, self-drilling or machine screw threads. Choose from a variety of drive styles including Spanner, Pin Head and Socket Pin Head, Torx, Opsit Reverse Thread and Tri-Wing, also known as triangular recess. Stainless steel security screws are most commonly manufactured; however, AFT also offers a few brass security screws with machine threads.
