Drywall screws are specialized fasteners designed to secure sheets of plasterboard, gypsum board, or drywall to wood frame studs or metal support channels without damaging the material.
Coarse thread drywall screws feature deep, wide threads that grip effectively into wood studs. Fine thread drywall screws are self-tapping and work best when securing plasterboard to light-gauge metal studs.
Self-drilling drywall screws are recommended when attaching plasterboard to heavy-duty metal framing. The integrated drill-point tip allows the screw to pierce and tap into thick metal without requiring a pre-drilled pilot hole.
Collated drywall screws come held together in plastic strips designed for auto-feed screw guns. They significantly speed up installation times, improve depth accuracy, and reduce operator fatigue on large contracting jobs.
Generally, the screw should penetrate at least 5/8 of an inch (approx. 15-16mm) into wood framing, or 3/8 of an inch (approx. 9-10mm) through metal studs. Always account for the thickness of the plasterboard sheet when measuring.
