Drywall Screws are specialized fasteners designed for securing drywall sheets to wooden or metal studs. Featuring sharp tips and fine or coarse threads, they provide easy penetration and a firm hold without damaging the drywall surface. Commonly used in construction and renovation, drywall screws are available in black phosphate, zinc plated, and stainless steel finishes for durability and corrosion resistance.
