Hefei SENOTECH New Materials Co., Ltd proudly presents our premium Zinc Plated Drywall Screws with Coarse Thread, specifically engineered for wood framing applications. As a reliable trading company established in 2020 with an annual export value of US$1 million to US$1.5 million, we serve customers across North America, South America, Europe, Asia, Africa, and Oceania. Our drywall screws are manufactured with stringent quality control, ensuring consistent performance and durability for professional contractors and DIY enthusiasts alike.
Our coarse thread design provides superior holding power in softwood and hardwood studs, reducing the risk of stripping and ensuring a secure attachment of drywall panels. Available in full sizes from 13mm to 100mm, these screws accommodate various drywall thicknesses and framing requirements. The zinc plating offers reliable corrosion resistance, while the high hardness (case hardened) construction ensures the screws can penetrate wood without bending or breaking.

Frequently Asked Questions
-
Q: Are these screws suitable for metal studs?
A: No, these are coarse thread screws designed specifically for wood framing. For metal studs, we recommend fine thread drywall screws. -
Q: What is the difference between coarse thread and fine thread drywall screws?
A: Coarse thread screws have wider, deeper threads that bite into wood quickly and provide better holding strength. Fine thread screws are designed for metal studs. -
Q: Can I use these screws outdoors?
A: The zinc plating offers limited corrosion resistance. For outdoor or high-moisture environments, we recommend using screws with additional coating (e.g., epoxy or stainless steel). Indoor use is ideal. -
Q: What lengths are available for immediate shipment?
A: We stock full sizes from 13mm to 100mm. Please contact us for current inventory and lead times for specific sizes. -
Q: Do you provide samples before bulk order?
A: Yes, we can send samples for quality evaluation. Sample fees may apply but will be deducted from your first order. -
Q: What is the typical packaging?
A: Standard packaging includes bulk boxes (1kg/5kg/25kg) or shrink-wrapped packs. Customized packaging with your branding is available upon request. -
Q: How do you ensure consistent hardness and quality?
A: We perform random hardness testing and torque testing on each production batch. Quality reports are available upon request. -
Q: Can you customize the thread pitch or head type?
A: Yes, we can accommodate custom specifications for large-volume orders. Please discuss your requirements with our sales team.
