Drywall screws are specifically designed for fastening drywall to metal or wood framing. These screws have a sharp, self-tapping thread that provides a secure grip and prevents the drywall from pulling away from the studs. They come in different types, including coarse, fine, and self-drilling screws. The bugle head design of drywall screws allows them to sink into the surface of the drywall without breaking the material, minimizing the risk of damage during installation. This head design also enables the screws to lie flush with the material, making them versatile for various construction tasks. When compared to nails, drywall screws offer superior holding power, grip, and tensile strength, ensuring a more secure and durable installation. It's important to avoid over-tightening drywall screws as they are hard but also brittle and can snap off if excessive force is applied.
