Welcome to Hefei SENOTECH New Materials Co., Ltd – your dedicated partner for premium fastening solutions. As a professional supplier with over US$1 million annual export value and serving markets across North America, South America, Europe, Asia, and beyond since 2020, we bring reliability and performance to every shipment. Our China Manufacturer Magazine Screws Plastic Strip Coarse Thread Yellow Zinc 25/35/40mm are engineered specifically for metal stud applications, offering outstanding holding power and corrosion resistance. Each screw is case-hardened to deliver high hardness, ensuring smooth penetration and reduced risk of breakage. Whether you're framing commercial buildings or residential partitions, these collated screws provide fast, consistent driving with your auto-feed screwgun.
Key Features & Technical Specifications
- Coarse Thread Design: Specially designed for metal studs (typically 20–25 gauge), the aggressive thread pitch ensures maximum grip and reduces strip-out in thin steel.
- Yellow Zinc Plating: Provides reliable corrosion protection for indoor and sheltered environments, extending fastener life.
- High Hardness (Case Hardened): Surface hardness of approximately 510–560 HV (available upon request) prevents screw deformation during installation, even when driving into harder steel.
- Collated in Plastic Strip: Pre-loaded strips (typically 50 pcs per strip) allow rapid sequential feeding with compatible screw guns, boosting installation speed by up to 50%.
- Three Popular Lengths: 25mm (1"), 35mm (1-3/8"), and 40mm (1-9/16") to accommodate various drywall layers and stud thickness.
- Bugle Head: Countersinks automatically without over-driving, creating a smooth dimple for easy finishing.
- Sharp Point: Sharp self-starting point eliminates the need for pre-drilling in most metal studs.

Frequently Asked Questions (FAQ)
-
Q: Are these screws suitable for wood studs?
A: While primarily designed for metal studs, the coarse thread can also grip soft wood. For best performance in wood, we recommend fine-thread drywall screws. Please consult our sales team for alternative options. -
Q: What is the maximum metal stud thickness these screws can penetrate?
A: They are optimized for 20–25 gauge steel (0.8–1.2 mm). Thicker steel may require pre-drilling or a different screw type. We suggest testing on your actual material. -
Q: Can I use these screws outdoors?
A: Yellow zinc provides limited corrosion resistance. For exterior or high-humidity environments, we recommend screws with more robust coatings (e.g., hot-dip galvanized or stainless steel). Contact us for custom options. -
Q: How are the screws collated? Are strips compatible with major screw guns?
A: Screws are collated on plastic strips with heat bonding. The 0° collation angle is compatible with most common auto-feed screw guns (e.g., Makita, Dewalt, Senco). 15° collation available upon request. -
Q: What is the typical hardness value?
A: Case hardness is ≥510 HV (about 50 HRC). Core hardness is lower to maintain ductility. This combination provides a good balance of strength and flexibility to prevent snapping. -
Q: Do you provide free samples?
A: Yes, we can provide a small free sample pack (50 pcs) for evaluation. Shipping cost to be covered by the buyer. Please contact us with your details. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 50 boxes (50,000 pcs) per size. For initial trial orders, we may consider smaller quantities – please inquire. -
Q: Can I customize the packaging or barcode?
A: Absolutely. We offer OEM services including custom boxes, labels, and barcodes. Lead time for customized packaging is typically 15–20 days.
