Drywall screws (sheetrock screws) are specialized self-tapping screws that usually feature a bugle head that is designed to attach drywall to studs, and a phosphate finish. In the construction industry, sheetrock screws have many alternative uses because they are relatively inexpensive, feature a flat head that is less prone to getting pulled through the wood, and thin, making these self tapping drywall screws less likely to split the wood. They are available with a coarse thread, fine thread, high-low pattern thread, and sometimes feature a trim head rather than a bugle head.
