This guide is for DIY enthusiasts and tradespeople working with plasterboard, wood, or metal. The Diall Fine Metal & Wood Plasterboard Screws offer a durable and reliable fastening solution for a variety of projects, ensuring a secure hold. A key consideration is their specific length and thread type, which may not suit all applications.

These screws are specifically designed for use in plasterboard, wood, and light gauge metal framing.
While the black phosphate coating offers some corrosion resistance, these screws are primarily intended for interior applications. For exterior use, screws with specific exterior coatings or stainless steel are recommended.
Partially threaded screws have an unthreaded shank near the head. This allows the threads to pull the material tightly against the head without the threads engaging in the top layer, which is beneficial in applications like attaching plasterboard to wood to prevent splitting and ensure a flush finish.
Yes, you can use these screws with a standard drill or impact driver. Ensure you use the correct driver bit and set the torque appropriately to avoid damaging the screw head or the material.
The black phosphate coating enhances the screw's durability by providing improved resistance to corrosion and rust. It also offers a non-reflective finish.
The exact number of screws in a 2kg pack can vary depending on the size and density of the screws. However, this pack size is intended to provide a substantial quantity suitable for medium to large DIY projects.
Pre-drilling is often recommended, especially when working with harder woods or metal studs, to ease insertion, prevent material splitting, and ensure the screw goes in straight. For soft plasterboard or softwoods, it may not always be necessary.
Ensure you are using the correct size and type of driver bit. Reduce the torque setting on your drill/driver. Consider drilling a small pilot hole in harder materials.
Check if the material is too soft or if the screw is too long/short for the application. For wood, ensure you are driving into a solid section. For metal, confirm the gauge is appropriate.
Ensure the material is suitable for countersinking. Apply steady pressure. If the material is very hard, a slightly larger pilot hole might be needed, or try a different screw type.
Ensure screws are stored in a dry, clean environment. If minor surface rust appears, it can often be wiped off; for significant corrosion, replace the screw.
Setup: These screws require a screwdriver or drill with an appropriate driver bit (typically Phillips or Pozidriv, check screw head recess). Ensure the drill/driver is set to a suitable torque setting to avoid overtightening, which can strip the thread or damage the material. A pilot hole may be beneficial in harder woods or thin metals to ease insertion and prevent splitting.
Compatibility: Ideal for use with plasterboard, drywall, timber, and light gauge metal studs. Ensure the material thickness and type are appropriate for the 70mm length and 4.2mm diameter. Not recommended for use in concrete or masonry.
Care: Store screws in a dry environment to prevent rust, despite the phosphate coating. Keep the pack sealed when not in use to avoid contamination.
