Our 3.5 x 55mm coarse thread drywall screws come in a box of 500 with a grey phosphate finish and PH2 bugle head. A coarse, widely spaced thread gives fast drive-in and strong pull-out resistance in softwood framing. At 55mm it's typically used for fixing up to two layers of 15mm to timber – always check the board manufacturer's fixing guidance.

FAQs
What is the 3.5 x 55mm size used for?
It's typically used for fixing up to two layers of 15mm 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%.
