Countersunk PH2 Drywall Screws 3.5 x 38mm Black Phosphate TUB 1000 S9DBB350380

This tub contains 1,000 black phosphate drywall screws, each measuring 3.5 x 38mm with a countersunk Phillips head. They are intended for fixing plasterboard and drylining sheets to both timber and metal stud work during partitioning or ceiling projects.

Trades typically use these screws for securing boards in place ahead of jointing, achieving a level surface ready for finishing. The 38mm length suits single-layer plasterboard over standard stud, with the phosphate coating helping to limit corrosion during installation in both interior and sheltered environments.
