Product Description

PRODUCT PARAMETER

DRYWALL SCREWS

Drywall screws are specialized fasteners for securing gypsum boards (drywall) to wooden or metal studs. They feature a thin shank, sharp point, and fine threads to minimize board cracking, with a Phillips or bugle head that sits flush without damaging the surface. Made of carbon steel (often zinc-plated for rust resistance), sizes range from 3.5–4.5mm diameter and 25–75mm length.

Applications:

Residential/Commercial Construction: Install wall and ceiling drywall, attaching to wooden studs or metal framing.
Renovations: Fasten drywall in room remodels, ensuring tight, crack-free connections.
Interior Finishing: Secure backing boards for tiles, insulation, or paneling.
DIY Projects: Ideal for home repairs or custom wall builds, compatible with power drills for quick installation.

Their design balances holding strength and gentleness on gypsum, making them essential for efficient, clean drywall installation.
