What Screws for Plasterboard?

Author : raz smiths | Published On : 24 Jul 2026

Choosing the right screw for plasterboard might seem like a small detail, but it plays a major role in the strength, durability, and finish of your project. Whether you're a professional tradesperson or tackling a DIY renovation, using the correct drywall screw helps prevent loose boards, damaged surfaces, and costly repairs later on.

This guide explains everything you need to know about selecting the right plasterboard screws for different applications in the UK.

Why Using the Right Plasterboard Screw Matters

Plasterboard is designed to create smooth, lightweight walls and ceilings, but it also requires specially designed fixings. Standard wood screws or general-purpose screws can tear the paper surface, reduce holding strength, and even cause screw pops after decorating.

Drywall screws are manufactured with a bugle head that sits neatly below the board's surface without damaging the paper face. This creates a cleaner finish while maintaining the board's structural integrity.

Fine Thread vs. Coarse Thread Screws

One of the biggest mistakes people make is choosing the wrong thread type.

Fine Thread Screws
These are specifically designed for fixing plasterboard to light-gauge metal studs. The tighter thread cuts through steel efficiently while providing a secure hold.

Coarse Thread Screws
These work best with timber studwork. Their wider thread grips wood fibres more effectively, creating excellent pull-out resistance and long-term stability.

Choosing the Correct Screw Length

Screw length should match both the plasterboard thickness and the substrate behind it.

Some common recommendations include:

  • 25mm: Suitable for thinner boards or face laminating plasterboard.

  • 32mm: Ideal for fixing standard 12.5mm plasterboard to metal studs.

  • 38mm: Commonly used for 12.5mm plasterboard fixed to timber framing.

  • 50mm: Recommended for thicker plasterboard on timber.

  • 75mm: Best for double-layer plasterboard installations.

As a general rule, the screw should penetrate at least 10mm into metal framing and approximately 25mm into timber for a reliable fixing.

Common Installation Mistakes to Avoid

Even high-quality screws won't perform properly if they're installed incorrectly.

Avoid these common issues:

  • Driving screws too deep and tearing the paper face.

  • Leaving screw heads proud of the surface.

  • Using timber screws for metal framing.

  • Choosing screws that are too short for the application.

  • Inconsistent screw spacing across the board.

Taking a little extra care during installation results in stronger walls, fewer callbacks, and a smoother finish for decorating.

Quality Fixings Deliver Better Results

Professional-looking plasterboard work isn't just about taping and plastering. The quality of the fixings underneath determines how well the installation performs over time.

Selecting the right thread type, correct screw length, and proper installation technique helps reduce movement, minimise cracking, and improve the lifespan of the finished wall or ceiling. Whether you're working on a new build, renovation, or commercial fit-out, using purpose-made drywall screws is one of the simplest ways to achieve a reliable result.
