Drywall Screw — Black
The standard indoor drywall screw
The black drywall screw is the one used on most interior jobs. The black colour is a phosphate coating, which stops the screws rusting in storage and gives the driver bit a little extra grip.

What it is used for
Use the black screw for normal indoor drywall work where there is no damp.
Indoor walls and ceilings
The standard choice for gypsum board partitions and false ceilings.
Invisible finish
The head dimples the board so it can be filled and painted over.
Lowest cost
The most economical of the three finishes for high-volume interior work.
Dry areas only
Not for bathrooms, kitchens, outdoors or anywhere that gets damp.
Overview
It is made for dry indoor work only. The coating offers very little rust protection, so it is not suitable for bathrooms, outdoor work or anywhere damp.
The bugle head presses a small dimple into the board face without tearing the paper, which is what lets you fill and paint over it invisibly.
Bugle head
Presses the board face into a dimple instead of cutting through it.
Sharp point
Bites immediately, which keeps high-volume fixing quick.
Two thread types
Fine for steel studs, coarse for timber.
Trade packs
Available in 250, 500 and 1000 piece boxes for site work.

Section 1 — Installation
How to fit it
Board fixing is all about depth. Every screw needs to sit just below the surface with the paper face still intact, and doing that a few hundred times in a row is what a depth stop is for.

- 1
Match the thread to the stud
Fine thread for steel studs, coarse for timber. A coarse thread in thin steel will just spin and never tighten.
- 2
Pick the right length
For 12.5 mm board, 25 mm on steel studs and 32 mm on timber. Add the second board thickness if you are double layering.
- 3
Use a depth stop
Set it so the head finishes just below the surface with the paper dimpled but not broken. This turns hundreds of judgement calls into one setting.
- 4
Press the board tight to the stud
Push the board firmly against the framing as you drive. Screwing across a gap is what causes screws to pop through the finish months later.
- 5
Follow the spacing
Roughly 200–300 mm along studs and 150–200 mm at board edges, staying 10–15 mm in from the edge.

Drywall Black — questions we get asked
Why are drywall screws black?
It is a phosphate coating. It stops the screws rusting in the box and gives the bit slightly better grip. It is not real rust protection, so these are for dry indoor use only.
Fine thread or coarse thread?
Fine thread for light steel studs, coarse thread for timber studs. Using coarse in thin steel is why screws sometimes spin without ever tightening.
What length for 12.5 mm board?
25 mm on steel studs, 32 mm on timber studs. Double the board and add the extra thickness.
Can I use these outdoors?
No. They will rust within one monsoon. Use the zinc drywall screw outdoors, or better still a proper exterior screw.
