• Fine thread for metal studs: made for drylining onto light-gauge steel stud and track up to 0.6mm. Grips fast without spinning.
• Bugle head: self-countersinks and pulls the board tight without ripping the paper liner, leaving a flush, ready-to-finish surface.
• Phillips PH2 recess: positive, low-cam-out drive for speed on the gun. A matched S2 driver bit is included.
• 25° sharp point: bites and penetrates quickly for faster boarding.
• 60° fine/twin thread form: high pull-out values with rapid insertion.
• Phosphate-coated carbon steel: dark grey/black finish suited to clean, dry interior use (Corrosion Rating 1).
• Fire Classification A1 and manufactured to BS EN 14566:2008: specification-grade for professional drylining.
• Trade pack quantities: 200/Box and 1000/Box, in lengths from around 25mm to 100mm.

Use these screws to fix plasterboard and drywall sheets to metal (steel) stud partitions, MF ceiling grids and drylining track up to 0.6mm steel thickness. Get the thread right and everything else follows:

• Fine thread (this product) → metal stud. The fine pitch cuts and holds in thin steel without stripping.
• Coarse thread → timber stud. A coarse pitch grabs and holds in wood. Use it on steel and it spins, slips and wastes fixings.

Typical trades: dryliners, plasterers, ceiling fixers and builders boarding out steel-framed partitions and suspended ceilings. Match the length to your board build-up. As a rough guide, allow at least 10mm of engagement into the stud beyond the board thickness.

What is the difference between fine and coarse thread plasterboard screws?

Fine thread plasterboard screws have a tighter pitch that cuts into and grips thin steel, so they're the ones for fixing plasterboard to metal studs. Coarse thread screws have a wider pitch that grabs and holds in wood, which makes them right for timber studs. Put coarse thread into metal and it spins and strips. Put fine thread into timber and the hold is weaker.

Which screws should I use for plasterboard on metal studs?

Fine thread plasterboard screws like these TIMCO bugle head screws. They're rated for steel stud and track up to 0.6mm thick and give a secure, spin-free fix. Just match the length to your board build-up so the screw fully engages the stud.

Are these the black plasterboard screws, and what is the finish?

Yes. They're sold as "Black" plasterboard screws. That dark grey/black colour comes from a phosphate conversion coating on carbon steel, which suits clean, dry interior conditions (Corrosion Rating 1). They aren't intended for exterior or damp environments.

What drive bit do I need?

A Phillips PH2 bit, and a matched S2 driver bit comes in the pack. The PH2 recess in the bugle head gives positive engagement with minimal cam-out on a screw gun or drill-driver.

What length drywall screw do I need?

Choose a length that passes through the board and engages the stud by roughly 10mm or more. These run from about 25mm up to 100mm. Single-layer boarding usually takes 25 to 38mm, while thicker or double-layer build-ups need longer screws.

Are TIMCO plasterboard screws fire rated?

They carry Fire Classification A1 and are manufactured to BS EN 14566:2008, which makes them suitable for specification-grade drylining work.

Order in 200 or 1000-piece trade boxes across the full length range. Boarding onto timber studwork instead? Choose a coarse thread drywall screw for that.
