Product Details
25mm Drywall Screws are specially designed for fixing plasterboard sheets to timber or metal studwork, making them ideal for building or repairing walls and ceilings in home improvement projects. These screws feature a black phosphate coating for corrosion resistance and a bugle head that sits flush with the board, preventing damage to the plasterboard surface. Their self-tapping, coarse thread design allows for quick and secure installation into wood or metal up to 0.8mm thick, using a standard screwdriver or drill. Commonly supplied in boxes of 1000, they are suitable for use with 12.5mm or 15mm single layer plasterboard. The term “drywall screws” is often used when fixing plasterboard, while “self-tapping” or “bugle head” may be specified for particular installation methods or finishes.

Frequently Asked Questions
What thickness of plasterboard are 25mm drywall screws suitable for?
25mm drywall screws are designed for single layer plasterboard installations, typically 12.5mm or 15mm thick boards. The 25mm length provides sufficient penetration into timber or metal studwork while preventing over-driving through the plasterboard surface.
Can 25mm drywall screws be used with metal studs?
Yes, these self-tapping drywall screws are suitable for both timber and metal studwork up to 0.8mm thick. The coarse thread design allows them to cut their own thread in metal studs, providing a secure fixing without pre-drilling.
How many 25mm drywall screws do I need per square metre of plasterboard?
Typically, you'll need 12-16 screws per square metre of plasterboard, depending on stud spacing and board size. For standard 400mm stud centres, use approximately 14 screws per m², spacing them 200-250mm apart along each stud.
What's the difference between 25mm and longer drywall screws?
25mm screws are specifically for single layer plasterboard (12.5-15mm thick), while longer screws like 32mm or 38mm are used for double-layer installations or thicker boards. Using the correct length prevents over-penetration and ensures proper fixing strength.
Do I need special tools to install 25mm drywall screws?
You can use either a standard screwdriver or drill with a Phillips head bit (usually PH2). For faster installation on larger projects, a drywall screw gun or drill with adjustable torque settings will prevent over-driving and damage to the plasterboard surface.
