42mm Black Drywall Screws Fine Thread (1000/Box)

42mm Black Drywall Screws for fixing plasterboard to light-gauge steel stud systems. 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 metal studwork, reducing driving effort and ensuring clean drive-through. The fine thread is optimised for light-gauge steel substrates, delivering controlled drive and secure engagement for consistent holding strength. 42mm length fixings suitable for double-layer plasterboard systems or dense board types on steel frameworks.
