Black Plasterboard Screws
(28 Products)Black plasterboard screws are specifically designed for securing plasterboard to timber or metal stud frameworks. Featuring a sharp, self-tapping point, they ensure quick and easy installation without the need for pre-drilling. Their bugle-shaped head prevents surface damage by distributing pressure evenly, reducing the risk of tearing the plasterboard paper. These screws owe their black exterior to their phosphate coating which protects the metal from rusting. This corrosion resistance is most common in coarse threads as they're typically used to apply plasterboard to timber, an application which presents a higher risk of damp and rust. We offer a range of black plasterboard screws, including fine thread screws, coarse thread screws, and collated screws.

What Are Black Plasterboard Screws?
Black plasterboard screws are specifically designed to attach plasterboard to framing. Plasterboard (otherwise referred to as wallboard) comprises a gypsum core that is enveloped in heavy paper. Plasterboard screws are specifically designed to pierce the skin of this paper coating, driving through to the gypsum core and affixing to the framing material on the other side.
Black plasterboard screws come with either coarse or fine threads, and the type chosen depends on the framing material - coarse for wood and fine for metal. The distinctive black coating that can be seen on black plasterboard screws is phosphate coating - a preventative measure against rust and corrosion.
Types of Black Plasterboard Screws
Coarse Thread Drywall Screws
- Ideal for securing plasterboard to timber studs.
- Provides a strong hold with reduced risk of loosening.
Fine Thread Drywall Screws
- Designed for fixing plasterboard to metal studs.
- Ensures a precise, firm grip and prevents movement over time.
- Often self-drilling, eliminating the need for pre-drilling.
Self-Drilling Plasterboard Screws
- Typically fine-threaded for metal framing.
- Features a drill tip for effortless penetration without pre-drilling.
Installation Best Practices
- Mark the Studs - Identify and mark the placement points to achieve consistent and accurate screw positioning.
- Use the Right Drill Bit - A Phillips or Pozidriv bit is recommended for optimal grip and reduced slippage.
- Drive in the Screws Correctly - Ensure that the screws penetrate smoothly without breaking the plasterboard surface.
- Maintain a Flush Finish - The bugle head should sit just below the surface, preventing protrusions that could affect wall finishing.
- Space Screws Appropriately - Screws should be placed every 200-300mm along the studs to maximise stability and strength.
Frequently Asked Black Phosphate Drywall Screws Questions
Can Black Plasterboard Screws Be Used In Damp Environments?
While black phosphate-coated screws offer some corrosion resistance, they are not ideal for damp environments. For wet areas, consider galvanised or stainless steel alternatives.
Are Black Plasterboard Screws Suitable For Attaching Heavy Objects To Drywall?
Plasterboard screws are designed to hold the board in place, but for attaching heavy objects, additional supports such as wall plugs, anchors, or toggle bolts are recommended.
