High-Performance 3.5mm-4.8mm Drywall Screws: The Standard for Modern Construction
Our 3.5mm-4.8mm Drywall Screws, also known as Gypsum Board Screws, are engineered to provide maximum efficiency and holding power in interior wall and ceiling installations. Featuring the iconic Bugle Head, these fasteners allow for a flush finish without damaging the gypsum paper. Whether you are a professional contractor or a large-scale hardware wholesaler, our Black Phosphated drywall screws offer the durability and speed required for high-volume residential and commercial projects.
As a leading drywall screw factory, we use premium C1022A case-hardened steel, ensuring every 3.5mm (#6) and 3.9mm (#7) screw has the strength to penetrate studs quickly while maintaining exceptional pull-out resistance.
- Self-Piercing Sharp Point: Designed for an immediate start into wood or light-gauge metal studs without the need for pre-drilling.
- Optimized Thread Designs: Choose Coarse Thread for superior grip in timber framing, or Fine Thread for secure fastening into cold-rolled steel studs.
- Superior Finish Options: Our Black Phosphated coating provides excellent paint adhesion and basic rust protection, while Zinc Plating offers enhanced corrosion resistance for humid environments.
- High-Speed Installation: Precision Phillips #2 drive reduces cam-out and ensures a consistent drive every time, increasing job site productivity.
Select the ideal metric drywall screw size based on your board thickness and framing material.

Our 3.5mm-4.8mm Gypsum Screws are essential for various construction sectors:
- Partition Walls: Fastening drywall panels to light steel keels in office and residential buildings.
- Ceiling Systems: Ideal for mounting plasterboard to overhead metal or timber grids.
- Soundproofing: Securely attaching acoustic panels to stud frameworks.
- Cabinetry: Using Coarse Thread screws for light-duty wooden frame attachments.
Q: When should I use Fine Thread vs. Coarse Thread?
A: Use Fine Thread screws for metal studs (they tap into the steel) and Coarse Thread for wooden studs (the aggressive threads grip the wood fibers better).
Q: Why is the head shaped like a bugle?
A: The Bugle Head design allows the screw to depress the surface of the drywall slightly without tearing the protective paper face, ensuring a perfect finish for mudding and taping.
