Countersunk PH2 Drywall Screws 3.5 x 25mm Black Phosphate TUB 1000 S9DBB350250

These 3.5 x 25mm black phosphate drywall screws are designed for fastening plasterboard or drylining sheets to timber or metal studwork on interior fit-out and refurb projects. Each screw features a hardened point to aid quick penetration into studs, helping speed up board fixing in both wall and ceiling applications.

The countersunk Phillips head sits flush with the board surface, supporting straightforward taping or finishing. Supplied in a tub of 1000, these screws are suited to larger projects where frequent restocking is impractical. The black phosphate coating offers resistance to surface rust during on-site handling and before the final decoration stage.
