Countersunk PH2 Drywall Screws 4.2 x 75mm Black Phosphate TUB 500 S9DBB420750

This pack of 4.2 x 75mm black phosphate drywall screws is intended for use when fixing plasterboard or drylining sheets to timber or metal stud frameworks. The length is suitable for tasks where boards need to be secured through multiple layers or thicker substrates.

The countersunk design allows the screw heads to sit flush, supporting a clean finish that’s ready for jointing or tape and fill. The PH2 Phillips drive type works with standard tool bits, making installation straightforward during both interior and exterior fit-out jobs.
