Drywall screws are specifically designed to secure drywall (gypsum board) sheets to either wood or metal wall studs, offering a secure hold and preventing shifting over time.
The black phosphate coating provides excellent corrosion resistance during construction and ensures better adhesion for drywall compounds, mud, and paint finishes.
Coarse thread screws are ideal for securing drywall to wood studs as they bite into wood quickly. Fine thread screws are self-tapping and work best when fastening drywall to light-gauge metal studs.
No, self-drilling drywall screws are engineered with a sharp drill-point tip that cuts through metal or wood framing on contact, eliminating the need for pre-drilled pilot holes.
The bugle head of the screw should sit slightly below the surface of the drywall face paper, creating a shallow dimple for compound coverage without tearing the paper layer itself.
