Carbon Steel Drywall Screws
Product Overview
Bugle head light gauge steel framing drywall screw is a dedicated fastener specifically designed for gypsum board installation in interior decoration, and is also the core supporting component of the light gauge steel framing gypsum board system. This screw is made of high‑quality low‑carbon steel substrate, treated with carburizing heat treatment and Cr6 passivation electroplated zinc process, balancing hardness, toughness, and rust resistance. The bugle countersunk head with cross drive recess, combined with a sharp‑point self‑tapping coarse thread, is specifically optimised for penetrating light gauge steel framing and fixing gypsum boards. It offers convenient installation and a smooth finished surface, and is one of the most widely used standard fasteners in ceiling and partition projects.
Product Applications
Indoor Ceiling Projects: Widely used in both residential and commercial gypsum board ceiling installations, fixing gypsum boards to light gauge steel framing, ensuring structural stability and a flat surface, suitable for living rooms, bedrooms, corridors, and various other indoor ceiling scenarios.
Lightweight Partition Construction: Used for fixing panels in light gauge steel framing gypsum board partitions, it is the standard screw for office, retail, and residential partition projects, ensuring overall strength and surface flatness of the partition walls.
General Drywall System Scenarios: Applicable to various indoor drywall systems, such as feature wall substrates, partial partitions, and reinforcement around access panels, making it an indispensable fastener in gypsum board installation projects.
Product Features
Bugle Head Prevents Board Damage: The gently sloping bugle countersunk head design does not pierce the paper face of gypsum board during driving, leaving a flat surface without bulging, facilitating subsequent joint compound application.
High Hardness for Easy Penetration: Surface hardness reaches HRC51; the sharp‑point self‑tapping design allows easy penetration through light gauge steel framing without pre‑drilling, with reduced risk of tip breakage.
Efficient Installation Design: The cross recess is compatible with standard power tools, providing tight engagement without slipping; the coarse thread drives smoothly and offers strong bite resistance against loosening.
Reliable Rust Protection: The Cr6 passivated electroplated zinc coating delivers excellent rust resistance, meeting the long‑term service requirements of indoor dry environments.
