Drywall screws are specialized fasteners designed for attaching drywall panels to wooden or metal studs. They typically have a sharp point and a coarse thread that helps them grip the material securely. The head of a drywall screw is usually flat or bugle-shaped, allowing it to sit flush with the surface of the drywall. These screws are made from steel and often have a coating to prevent rust. They come in various lengths and diameters to accommodate different thicknesses of drywall. Using the right type of drywall screw is essential for ensuring a strong and durable installation.
