Plasterboard screws, commonly known as drywall screws, are specifically designed to secure sheets of plasterboard or drywall to wood or metal framing members. They feature a bugle head that sinks cleanly into the board surface without tearing the paper cover.
Coarse thread screws are ideal for fastening plasterboard to wood studs, as they grip the wood fibers tightly. Fine thread screws are self-tapping and designed for fastening to metal studs, as they cut through thin metal walls more cleanly.
The black phosphate coating provides standard rust and corrosion resistance. It also creates a textured matte finish that helps plaster, joint compound, and paint adhere better to the screw head once it is driven in.
No, self-drilling drywall screws have a drill-point tip that acts like a drill bit. They are designed to drill their own hole and tap their own threads in one single operation, which is highly efficient for metal studs.
For standard 12.5mm (approx. 1/2 inch) plasterboard fixed to timber studs, a screw length of 32mm to 38mm (1-1/4 to 1-5/8 inches) is typically recommended to ensure a secure penetration depth into the framing.
