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 anti-theft 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.
Screws with a triangle head are most commonly referred to as triangular or tri-head screws. They are a type of fastener that features a three-sided, or triangular, head. This type of head is seen most often in sheet metal screws, but can also be used for a variety of other applications.
Triangular screws are usually installed with an allen key, although some come with a built-in screwdriver slot. This type of head is designed to give more torque than a standard screw head and is commonly used in places where extra strength and security is needed.
