Welcome to Hefei SENOTECH New Materials Co., Ltd, a trusted supplier in the global construction fasteners market. As a trading company established in 2020 with an annual export value of US$1 million to US$1.5 million, we serve diverse markets across North America, South America, Europe, Asia, Africa, Oceania, and the Middle East. Our Factory Supply Collated Fasteners with Fine Thread and Black Phosphate are engineered for professional drywall installers who demand consistent quality, reliable feed, and no-jamming performance. With lengths of 25mm, 35mm, and 40mm, these fasteners are optimized for different drywall thicknesses and stud materials, ensuring a secure and efficient installation process. Backed by strict quality control and competitive pricing, our product is your go-to solution for large-scale drywall projects.
Key Features & Specifications
- Fine Thread Design – The fine thread (typically 20-40 TPI) provides superior holding power in metal studs and reduces the risk of stripping in thinner gauge steel. It also minimizes breakout on the back side of the drywall.
- Black Phosphate Surface Treatment – Offers excellent corrosion resistance and a dark finish that blends well with most wall surfaces. The phosphate coating also reduces friction during driving, contributing to smoother feeding.
- High Hardness – Our fasteners undergo heat treatment to achieve a core hardness of ≥50 HRC and surface hardness ≥550 HV. This ensures the screws penetrate drywall and studs without bending or breaking, even in high-volume applications.
- No-Jamming Collation – Each screw is precisely collated on durable plastic strips (or welded paper tape) with uniform spacing. This eliminates misfeeds and jams in auto-feed screw guns, saving time and reducing material waste.
- Sharp Needle Point – The self-drilling point starts easily and reduces the need for predrilling, speeding up installation.
- Available Lengths – 25mm (for 12.5mm drywall on wood studs), 35mm (for 15mm drywall or double layers), and 40mm (for heavy-duty or multiple layer applications). Custom lengths available upon request.

Performance & Installation Benefits
Our collated fasteners are designed to maximize productivity on job sites. Here's how they deliver value:
- Reduced Downtime – The no-jamming collation ensures continuous operation, with fewer interruptions to clear screw strips. This can improve installation speed by up to 30% compared to loose screws.
- Consistent Countersink Depth – The bugle head sinks perfectly into the drywall paper without tearing, creating a smooth surface for taping and finishing.
- Versatility – Suitable for both 0.5mm to 1.5mm metal studs and wooden studs. The fine thread grips firmly in metal, while the sharp point pierces wood easily.
- Corrosion Protection – Black phosphate coating provides adequate protection in indoor environments. For high-humidity areas, an optional wax or epoxy coating is available.
- Eco-Friendly Packaging – Our collation strips are made from recyclable plastic, and we offer bulk packaging options to reduce waste.

Frequently Asked Questions (FAQ)
-
Q: Are these fasteners suitable for both wood and metal studs?
A: Yes, the fine thread is optimized for metal studs (up to 1.5mm thickness), while the sharp point also works well in wood studs. For best results, we recommend using a drywall screw gun with adjustable depth. -
Q: Do these screws have any corrosion resistance?
A: The black phosphate coating provides a moderate level of corrosion resistance suitable for indoor drywall applications. For outdoor or high-humidity environments, please inquire about our optional epoxy or zinc coating upgrades. -
Q: How many screws come per strip?
A: Typically, each strip contains 30 to 60 screws, depending on the length and collation type. Please specify your preferred strip count when ordering. -
Q: Can I get samples before placing a bulk order?
A: Yes, we offer free samples (you pay shipping) for quality evaluation. Contact our sales team to arrange sample delivery. -
Q: What is the minimum order quantity (MOQ)?
A: The MOQ is typically 50,000 pieces per size, but we can discuss smaller trial orders for new customers. -
Q: How do you prevent jamming in screw guns?
A: Our collation strips are precision-molded with consistent screw spacing and alignment. We also use high-quality plastic that maintains rigidity under pressure. Additionally, the screws have a smooth shank design to reduce friction. -
Q: Can you provide custom lengths or coatings?
A: Absolutely. We offer customization in lengths (20mm to 60mm), coatings (zinc plated, black oxide, etc.), and head types (flat head, hex head). Please provide your specifications for a quote. -
Q: What packaging options are available?
A: Standard packaging includes 1000-screw boxes or 5000-screw bulk cartons. For OEM, we can print your brand on boxes and strips.
