Our 4.2 x 75mm coarse thread drywall screw, in a box of 500, is a black phosphate screw built for everyday drylining on site. The deep coarse thread bites hard into timber studs, joists and battens, pulling the board tight to the frame. At 75mm it's typically used for fixing up to thick insulated plasterboard to timber – always check the board manufacturer's fixing guidance.

FAQs
What is the 4.2 x 75mm size used for?
It's typically used for fixing up to thick insulated plasterboard to timber. As a rule of thumb, allow roughly 20–25mm of penetration into timber or 10mm into steel, and always follow the board manufacturer's fixing guidance.
Coarse or fine thread – which do I need?
Use coarse thread drywall screws for fixing board to timber studs and battens, and fine thread drywall screws for light-gauge metal studs and track up to 0.6mm.
Do these count towards the Site Pack discount?
Yes – drywall screws are part of our Site Pack, so mixing them with other eligible screws and fixings can save you up to 15%.
