Drywall screw

These drywall screws are made from C1022 carbon steel and undergo heat treatment after forming to enhance hardness and tensile strength. Available in both bugle head and countersunk head styles, they are designed for secure fastening into wood and metal framing. The drive type is Phillips, and surface finishes include black, gray phosphate, and yellow or blue zinc plating.

The material undergoes post-fabrication hardening, which differentiates it from standard phosphate-coated screws that rely only on surface treatment. This process improves thread retention under torque and reduces the risk of breakage during installation. The finishes provided are typical for industrial-grade drywall screws in China, with zinc plating offering moderate corrosion resistance suitable for interior use.

These screws are commonly sourced by builders and distributors supplying drywall installation teams in Southeast Asia and the Middle East. They are used primarily in residential construction for attaching gypsum board to wooden or light-gauge steel studs. Packaging is in bulk cartons, with standard weights of 10kg to 20kg. Trade terms are typically FOB Tianjin, with lead times dependent on order volume and finish availability.
