Welcome to Hefei SENOTECH New Materials Co., Ltd – your trusted sourcing partner for premium construction fasteners. We specialize in supplying high-performance Auto-feed Drywall Screws with Fine Thread, White Zinc Plating, and Plastic Strip Collation, available in the most demanded lengths of 25mm, 35mm, and 40mm. These screws are designed to streamline your drywall installation process, offering consistent feeding and powerful holding power without stripping. With our factory-direct supply chain and deep experience serving markets across North America, South America, Europe, and beyond since 2020, we ensure every batch meets rigorous quality standards at competitive prices.
Our auto-feed drywall screws are engineered for professional contractors and volume builders who demand efficiency. The fine thread design reduces friction during driving, allowing faster installation while maintaining a strong grip in steel studs and wood framing. The white zinc coating provides reliable corrosion resistance for interior applications, and the plastic strip collation ensures jam-free feeding in all major auto-feed screwdrivers. Whether you are working on residential, commercial, or industrial projects, these screws deliver consistent performance every time.
Key Features & Technical Specifications
- Auto-Feed Compatible: Precision-engineered plastic strip fits most auto-feed drywall screwdrivers (e.g., Senco, Hitachi, Makita, etc.), enabling rapid, one-handed operation.
- Fine Thread Design: Deeper, sharper threads cut quickly into steel studs (up to 20 gauge) and reduce the risk of over-torquing. Ideal for metal framing applications.
- White Zinc Plating: Uniform coating offers good protection against moisture and low-level humidity, suitable for interior drywall projects.
- Bugle Head Profile: Countersunk head design ensures flush finish with drywall surface, preventing tearing of paper facing.
- Phillips #2 Drive: Standard cross-drive provides excellent bit engagement and reduces cam-out during high-speed driving.
- Length Options: Available in 25mm, 35mm, and 40mm – the most common sizes for single-layer and double-layer drywall attachment.
- Reliable Strip Construction: Plastic strip made from durable, recyclable material that resists breakage even in cold temperatures.
- Consistent Quality Control: Each batch undergoes hardness testing, thread geometry verification, and adhesion strength checks before shipping.

Beyond the basic specifications, our auto-feed drywall screws offer tangible benefits for your business: Reduced labor costs – one operator can install up to 5000 screws per hour using an auto-feed tool; Less material waste – consistent strip collation eliminates dropped or misplaced screws; Improved finish quality – fine thread minimizes surface dimpling and reduces the need for secondary sanding. The white zinc coating, while not for exterior use, provides ample protection for indoor environments and helps screws drive smoothly without galling.

Frequently Asked Questions (FAQ)
1. What is the difference between fine thread and coarse thread drywall screws?
Fine thread screws have more threads per inch and are designed for steel studs (metal framing). They cut into metal efficiently and provide strong holding power. Coarse thread is better for wood studs. Our screws feature fine thread as specified.
2. Are these screws suitable for exterior use?
No, the white zinc plating is intended for interior applications (drywall attachment). For exterior or high-humidity environments, we recommend stainless steel or painted/coated screws – contact us for alternatives.
3. Can I use these screws with any auto-feed screwdriver?
Yes, the plastic strip collation is designed to fit most leading brands (Senco, Hitachi, Makita, DeWalt, etc.). The strip width and screw spacing are standard. If you have a specific tool model, please confirm compatibility with our sales team.
4. What lengths are available for immediate shipping?
We currently stock 25mm (1"), 35mm (1-3/8"), and 40mm (1-9/16") as standard. Other lengths like 45mm, 50mm, or 55mm can be produced with minimum order quantity – please inquire.
5. Do you offer private labeling or custom packaging?
Absolutely. We can print your brand logo on the boxes and even on the strip if required. Custom packaging (e.g., poly bags, bulk cartons) is also available. Minimum order quantities apply.
6. How many screws are on each plastic strip?
Typically 12 screws per strip for 40mm length, 15 screws per strip for 25mm length. The strips are joined into coils of 1000 screws per box.
7. What is the lead time for bulk orders (e.g., 100,000 pieces)?
For standard lengths, lead time is 10–15 days after confirmation. For custom specifications, please allow 20–25 days. We can expedite for urgent orders based on stock availability.
8. Do you provide samples before bulk purchase?
Yes, we offer free samples (you pay shipping). Samples are shipped within 3 days. Please contact us with your shipping address and required quantity (usually 20–50 screws are sufficient for testing).
