25mm Black Drywall Screws Coarse Thread (1000/Box)

25mm Black Drywall Screws for securing plasterboard to timber studs or joists. Each screw is manufactured from hardened carbon steel with a black phosphate coating that provides light corrosion resistance and a clean, low-glare finish. The bugle head ensures a smooth, flush seating without tearing the board’s paper surface, achieving a professional, ready-to-fill finish. A sharp W-type gimlet point allows easy penetration and rapid engagement into timber, reducing driving effort. The coarse thread is optimised for wood substrates, delivering strong bite and resistance to pull-out in natural grain. 25mm length is ideal for thin boards, edges, and single-layer plasterboard installations. Supplied uncollated for precise placement control in small and medium-sized projects.
