Drywall Screws Fine Thread

These are specialised fasteners that secure plasterboard to metal studs or track, and sometimes wooden battens. They have lots of closely spaced threads that bite into metal firmly and are usually finished with a black phosphate finish or zinc coating.

Phosphate reduces driving friction and offers light corrosion protection, but it is not suitable for damp or exterior conditions. Though less common for drywall applications, zinc-coated versions resist corrosion better.

What Are Fine Drywall Screws?

They are long, thin, fine-thread screws that are used to fasten plasterboard (gypsum panels). Their tightly packed spirals hold onto thin metal framing without tearing or slipping. Their heads are designed to penetrate the plasterboard panel without ripping the paper face.

Phosphate finish reduces friction and gives some corrosion resistance. Terms like phosphate fine drywall screws and black fine drywall screws are commonly used for this finish.

Sizes vary. There are 35mm fine drywall screws, ideal for single or double-layer plasterboard fixing to metal framing, as well as standard lengths like 25mm, 32mm, 42mm, and 50mm. Longer ones measuring 75mm and 100mm are also available from Insulation Wholesale.

What Are Fine Thread Drywall Screws Used For?

Typically used when fixing gypsum boards to metal studs or track where steel is relatively thin.

Fine-thread versions are meant for light-gauge steel only, often up to about 0.9 mm thick. Their fine threads pull the board tight against the frame and will not tear the metal. Thicker steel requires self-drilling (TEK) drywall screws.

Drywall fine thread screws also work into thin wood battens, though they do not grip wood as firmly as coarse thread versions.

What is fine thread drywall screws used for?

1. Fixing gypsum boards onto light-gauge metal studs – threading is locked in without tearing the frame.
2. Fixing boards to achieve a neat finish without damaging the sheet.
3. In some cases, securing boards to thin timber battens – although coarse threading pulls faster in wood.

How many fine thread drywall screws per plasterboard?

Here’s a good rule of thumb:

• Drive the screws about 300mm apart around the edges of the board.
• Drive the screws about 300–400mm apart across the centre of the board.

For a standard sheet, that often results in 30–50 screws depending on stud spacing and board size. The aim is to ensure the board stays flat and does not bow over time.
