At Hefei SENOTECH New Materials Co., Ltd, we specialize in providing high-performance fastening solutions tailored for modern construction. As a dynamic trading company established in 2020 with an annual export value of US$1 Million - US$1.5 Million, we have built a solid distribution network across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. Our Drywall Screws Fine Thread for Metal Studs represent the perfect balance of quality and affordability, designed specifically for fast and secure attachment of drywall to steel framing.
These screws feature a black phosphate coating that provides excellent corrosion resistance and a smooth driving experience. The fine thread design ensures maximum grip in metal studs without stripping, while the sharp point and fast penetration geometry reduce installation time and labor costs. Available in full sizes from 13mm to 100mm, they cover all common drywall thicknesses and stud gauges.
Key Product Features
- Fine Thread for Metal Studs: Unlike coarse threads for wood, our fine thread profile engages securely with thin steel, reducing the risk of spin-out or loosening.
- Black Phosphate Surface: This coating not only provides excellent rust protection but also reduces friction during driving, preventing cam-out and bit wear.
- Fast Penetration Design: The sharp needle-point and optimized flute geometry allow the screw to bite into metal quickly without pre-drilling, saving significant installation time.
- Full Size Range (13mm - 100mm): From 1/2-inch to 4-inch lengths, we offer every common size to meet diverse project requirements. Custom lengths available upon request.
- High Hardness & Strength: Manufactured from hardened carbon steel, these screws withstand high torque without snapping, ensuring reliable performance in demanding applications.
- Bugle Head Shape: The countersunk bugle head does not tear the paper surface of drywall, providing a smooth finish ready for joint compound.

Frequently Asked Questions (FAQ)
Q1: What is the difference between fine thread and coarse thread drywall screws?
Fine thread screws have more threads per inch and are designed specifically for metal studs. They grip the thin steel better without stripping. Coarse thread screws are meant for wood studs. Using the wrong type can cause security issues or damage the stud.
Q2: Can these screws be used for both drywall and other materials?
They are optimized for drywall attachment to metal studs. For other applications like attaching to wood or thicker steel, please consult our team for appropriate screw recommendations.
Q3: Are the screws corrosion resistant?
The black phosphate coating provides good corrosion resistance for indoor environments. For outdoor or high-humidity applications, we recommend using our galvanized or stainless steel options (available upon request).
Q4: How do I choose the correct length?
A general rule: the screw should penetrate the metal stud by at least 10mm (3/8 inch). For a 12.7mm (0.5 inch) thick drywall, use a 25mm (1 inch) screw. For double layer drywall, add the thickness of both layers plus 10mm.
Q5: What packaging options do you offer?
Standard packing is 1,000 screws per box with 10 boxes per carton. We also offer bulk packs, polybags, or custom branding for OEM orders. Minimum order quantity may vary.
Q6: Do I need to pre-drill holes before using these screws?
No. The sharp point and special flute design allow them to self-drill into metal studs up to 1.2mm thickness without pre-drilling. For thicker steel, a pilot hole may be needed.
Q7: Are these screws suitable for use with an automatic screw feeder?
Yes, they are compatible with most collated screw systems and automatic feeders. The Phillips drive and consistent geometry ensure smooth feeding.
Q8: How can I request a sample to test the quality?
We provide free samples for evaluation (shipping cost may apply for international orders). Please contact us with your required size and quantity, and we will arrange shipment promptly.
