3.8×25-38mm Carbon Steel Mesh Head Drywall Screws

Product Features
High-Low Thread Design, Efficient and Effortless Without Slipping: It utilizes a high-low variable pitch thread structure, where the high thread is responsible for quickly cutting the gypsum board and guiding the screw in, while the low thread is responsible for forming a secure bite within the light steel stud or wood. This significantly reduces driving resistance, prevents slipping during installation, avoids over-driving through the gypsum board, effectively eliminates board edge collapsing or cracking issues, and improves construction efficiency.
Phillips Countersunk Head + Anti-Slip Mesh, More Stable Installation: The Phillips recess fits universal driver bits, offering strong compatibility and reducing bit wear. The countersunk design allows the head to be fully embedded into the surface of the gypsum board, without affecting subsequent putty scraping and painting processes. The anti-slip mesh texture on the head increases friction with the contact surface of the gypsum board, preventing the screw from slipping during driving and ensuring a uniform and consistent countersunk depth.
Highly Corrosion-Resistant Eco-Friendly Coating, Suitable for Multiple Scenarios: The surface is treated with a chromium-free, highly corrosion-resistant coating, which not only provides an aesthetic light purple matte appearance but also possesses excellent rust and moisture resistance. Its salt spray test performance far exceeds that of traditional phosphated screws, making it suitable for gypsum board installation in damp environments such as bathrooms and kitchens, resulting in a longer service life.
Strong Specification Adaptability, Meeting Different Construction Needs: The 3.8mm diameter paired with the 25mm-38mm length range can accommodate gypsum boards of various thicknesses (9.5mm / 12mm / 15mm) and light steel studs or wooden studs of different specifications. It requires no additional pre-drilling and can be directly driven in to complete the fixation, offering strong versatility and reducing construction material stocking costs.
