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 to a standard drill, installers also use a tool known as a drywall simpler, 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 colouring 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 compounds or paint.
- The primary benefit offered by drywall screws is their Bugle Head. This means that the entire screw lies flush with the surface of the sheet, creating a smooth and even finish.
- Less prone to getting pulled through the wood due to Bugle Head.
- This type of head also helps prevent the drywall screw from breaking the paper surface, a common problem with nails.
- Drives fast and efficient.
- The black head adds to the decorative appeal.
- Fairly thin, so they are less likely to split the wood.
- Threaded through entire length thereby maximizing gripping power.
- Good Corrosion resistance due to black phosphate coating.
- Easy to install and remove.
- Head does not sink into the wood easily as does with other wood screws.
- Precise cutting edges to improve drill performance with less effort.
- Relatively Cheap.
- At least 3 times the pull-out strength of nails.
