FAQs
What is the 4.2 x 75mm size used for?
It's typically used for fixing up to thick insulated plasterboard to light-gauge steel. 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?
