Description
What are 3.5 x 38mm Plasterboard Screws used for?
Plasterboard screws of this specific size are the go-to fixing for internal wall construction in the UK. The 38mm length is perfectly calibrated to pass through a standard 12.5mm plasterboard sheet and provide deep, secure penetration into timber studs. Whether you are building a new partition wall, a ceiling, or a stud-work enclosure, these plasterboard screws provide the structural integrity required to prevent board movement and “popping.”
Why Choose Black Phosphate for Timber Studs?
The black phosphate coating on these plasterboard screws is more than just a finish; it acts as a dry-film lubricant. This allows the screw to be driven at high speeds by an electric screwdriver with minimal heat buildup. Furthermore, the phosphate layer prevents the screw from reacting with the moisture in the plaster or the natural acids in the timber, ensuring your walls remain free from rust spots (bleeding) over time.
Engineered for a Professional Flush Finish
At ECO HEAT SHOP, we supply fixings designed for a “skim-ready” finish. These plasterboard screws feature a bugle head, which is uniquely shaped to depress the surface of the plasterboard without snapping the delicate paper fibers. This creates a small indentation that can be easily filled with joint compound or covered with a finishing plaster coat, resulting in a perfectly flat wall surface.

Installation Advice: When using these plasterboard screws, set your drill torque so the head sits roughly 1mm below the board surface. Avoid over-driving, as breaking the paper skin significantly reduces the screw’s ability to hold the board securely against the timber frame.
