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. Button head screws are typically used for general purposes with a lower crown & shallower recess than round head screws.
