Security fasteners provide an added level of security by their drive design that prevents removal with ordinary screw drivers. Maximum torque transfer & positive tool engagement means easier drive installation with less pressure & slippage. Requires matching driver bit.
Truss Head screws are low profile and offer added security against vice-grip removal. They typically have large diameter heads for increased fastening strength.
