Black Phosphate Drywall Screws

Black phosphate drywall screws are dedicated fasteners for securing gypsum boards, light steel frames, wooden frames and interior decoration components. Manufactured from carbon steel and finished with black phosphating, they deliver smooth driving, firm clamping and basic rust resistance. The bell-shaped countersunk head ensures the screw head embeds neatly into the board surface, and the sharp tip allows for quick positioning and easy screwing. They are well-suited for decoration projects, building materials wholesale, hardware sales and bulk procurement.
