Drywall Screws – Carbon Steel – Indoor Use

Product Overview

These 25mm drywall screws with a coarse thread are perfect for securing plasterboard to timber studs or joists using auto-feed screwdrivers. Crafted from hardened carbon steel and coated with black phosphate, these screws offer light corrosion resistance and a sleek, low-glare finish.

The bugle head design ensures a smooth, flush seating without tearing the paper surface of the board, delivering a professional, ready-to-fill finish. The sharp W-type gimlet point allows for easy penetration and rapid engagement into timber, minimizing driving effort. The coarse thread is optimized for wood substrates, providing a strong bite and resistance to pull-out in natural grain.
