Drywall screws are specialized fasteners designed to securely attach drywall sheets to wood or metal studs. They have a bugle-shaped head that sits flush with the drywall surface and a sharp, self-tapping tip for easy penetration. Typically made of hardened steel and coated to resist corrosion, these screws feature coarse threads for wood or fine threads for metal applications. Their design prevents damage to the drywall and ensures a strong, lasting hold.
