Product Details
Product Introduction
22A drywall screws (1022A material wallboard screws) are manufactured from SWRCH22A cold‑forged carbon steel wire, undergo carburizing and quenching for hardening, and feature a flared cross‑recess head. They are available in coarse‑thread and fine‑thread versions, with black or gray phosphating surface finishes. These self‑tapping screws are specially designed for gypsum board and light‑steel framing applications in construction projects; they require no pre‑drilling, ensuring efficient installation, and are widely used for interior partition walls, suspended ceilings, and panel fastening.
Core Product Features
22A: Dedicated carbon steel substrate, heat-treated for enhanced hardness, delivering strong torque and preventing nail breakage or thread stripping during driving.
The horn‑shaped countersink design allows the screw to be fully recessed into the panel surface, ensuring a smooth, flush finish after puttying.
Standard PH2 Phillips head, compatible with standard screwdriver bits, ensures smooth, high-speed driving without slipping or stripping the screw slot.
The fine‑thread version is suitable for light‑gauge steel framing, with smooth tapping and strong clamping force; the coarse‑thread version is designed for timber joist substrates, providing secure and reliable fastening.
Phosphating surface treatment provides inherent lubrication, reduces driving resistance, and offers basic rust‑preventive properties.
The tip is sharp and can directly penetrate gypsum board, calcium silicate board, thin sheet metal, and wood panels without the need for pre-drilling.
The threads are uniform and free of burrs, reducing the risk of board chipping and ensuring durable anchorage that resists loosening.
Available in a full range of specifications, covering both residential and commercial construction needs; boxed packaging facilitates on-site storage and bulk purchasing.
