55mm Black Drywall Screws Coarse Thread Collated (1000/Box)

55mm Black Drywall Screws Collated Coarse Thread for fixing double-layer plasterboard to timber stud systems using auto-feed screwdrivers. 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. 55mm screws provide extended reach for securely fixing thicker or double-layer plasterboard to deeper timber framing. Supplied collated on strips for rapid, continuous fixing in high-volume installation work.
