Buying guide
How to specify drywall screws
Three decisions that prevent most problems on site.
Coarse or fine thread
Coarse thread grips timber studs; fine thread (and drill-point versions) is for light-gauge steel studs up to 0.9 mm.
Length rule of thumb
Choose a screw that penetrates at least 16 mm into timber or 10 mm past steel. For 12.5 mm board, 25 mm (#6 × 1") is the common size.
Collated for volume
Plastic-strip screws reduce install time on large fit-outs. We match strip pitch to common auto-feed tools on request.

Drywall Screws: common questions
Why are drywall screws black?
The black or grey colour comes from phosphate coating, which gives light corrosion protection and helps joint compound adhere.
Can drywall screws be used outdoors?
No. Phosphated screws are for dry interior use. For damp areas use zinc-plated or cement-board screws.
What sizes do you stock?
From 3.5 × 16 mm to 4.8 × 150 mm in metric, and #6 to #10 by 1" to 3" in inch sizes.
