Product Description

Product Description

This rust-proof zinc plated drywall screw is a professional fastening accessory for interior construction, specially designed for fixing gypsum boards, light steel keels and partition boards. Made of high-quality carbon steel with zinc plating treatment, it has excellent corrosion resistance, effectively preventing rust and oxidation, and ensuring long-term durability in indoor use.
 
Featured with a sharp self-tapping point, it can directly penetrate building materials without pre-drilling, which makes construction smoother, reduces board cracking and improves work efficiency greatly. The optimized fine thread design provides strong bite force and anti-loosening performance, ensuring stable and firm fixing effect. The standard Phillips countersunk/bugle head fits closely to the surface after tightening, keeping the installation surface flat and beautiful.
 
All specifications are manufactured in accordance with industry standards, with precise size, fine workmanship and no burrs or slipping. It is compatible with electric screwdrivers and other conventional construction tools, easy to operate, and is the ideal choice for residential and commercial decoration construction.
