Security fasteners offer enhanced security through a drive design that inhibits removal with standard screwdrivers. They provide maximum torque transfer and positive tool engagement, facilitating easier drive installation with reduced pressure and slippage. A matching driver bit is necessary for use. Button head screws, characterized by a lower crown and shallower recess compared to round head screws, are typically utilized for general purposes.
