Coarse thread drywall screws feature sharp, wide threads designed specifically for securing drywall to wood studs. Fine thread drywall screws have tighter, self-threading designs suitable for fastening drywall to metal framing studs.
The black phosphate coating provides reliable rust and corrosion resistance during construction. Additionally, this chemical treatment creates a matte texture that improves the adhesion of drywall joint compounds, paint, and primers.
Self-drilling (drill-point) drywall screws should be used when mounting plasterboard onto heavy-gauge metal studs. The integrated drill-shaped tip cuts through the metal without needing a pre-drilled pilot hole.
Collated drywall screws are assembled on plastic strips designed for auto-feed screw guns. They drastically speed up installation times, reduce screw wastage, and permit one-handed operation during major boarding projects.
Drywall screws should be driven until the bugle head rests slightly below the paper surface, creating a shallow dimple without breaking the paper liner. If the paper tears, the screw loses its holding strength.
