drywall screw is a specialized self-tapping screw with a cylindrical shaft. these screws almost always have a phillips bulge head rather than a slotted head, which provides additional control for installers. in addition of a standard drill, installers also use a tool known as a drywall dimpler, which has an adjustable nose to install a drywall screw without tearing the paper on each sheet.
a standard drywall screw can be readily identified by its black finish. this black coloring comes from a phosphate mineral coating that is applied to these screws. this coating helps to minimize rusting and corrosion as the screws are exposed to wet joint compound or paint.
