Fine thread drywall screws feature dual threads designed primarily for securing drywall sheets to light-gauge metal studs. Coarse thread drywall screws have wider, aggressive threads optimized for maximum grip when fastening drywall to wooden framing.
Long plasterboard screws are essential for installing double layers of plasterboard, attaching thick soundproof or fire-resistant drywall, or fixing boards over insulation where extra penetration depth into wood or metal framing is required.
Collated drywall screws come pre-loaded onto durable plastic strips, designed for auto-feed screw guns. This system enables rapid, one-handed installation, reduces physical strain, and cuts down on screw waste in large-scale residential and commercial projects.
Yes, plasterboard to plasterboard screws are specifically designed to laminate or join two layers of drywall together. Their special thread design provides exceptional holding power directly within the core of the plasterboard without needing to line up with a wall stud.
Most standard drywall screws feature a bugle head style that countersinks into the drywall paper without tearing it. They typically utilize a Phillips #2 drive, which ensures a secure fit with the screwdriver tip for precise depth control.
Drywall screws are commonly treated with a black phosphate or zinc coating. This coating provides moderate rust resistance during the construction process and protects the screw from reacting to the moisture present in joint compounds and plaster.
