Professional Grade Coarse Thread Auto-feed Screws – designed to deliver fast, reliable drywall fastening for contractors and builders worldwide. As a trusted supplier from Hefei SENOTECH New Materials Co., Ltd, we ensure every screw meets rigorous industrial standards. Our yellow zinc coated finish provides excellent corrosion resistance, while the plastic strip collation guarantees smooth feeding in auto-feed screw guns, reducing downtime and labor costs.
These screws feature coarse threads that bite quickly into wood or metal studs, minimizing “cam-out” and stripping. Available in 25mm, 35mm and 40mm lengths, they are ideal for single-layer or double-layer drywall applications. The bugle head design automatically countersinks, creating a flush finish for easy taping and jointing.
Key Features & Benefits:
- Coarse Thread Design: Provides superior holding power in wood framing and pre-drilled metal studs, reduces the risk of screw slip-out.
- Yellow Zinc Plating: Achieves 72+ hours salt spray resistance (test data available upon request), ideal for dry environments or light humidity.
- Plastic Strip Collation: 100% compatible with leading auto-feed tools (e.g., Senco, Paslode, Makita); each strip holds 60 screws for continuous operation.
- Bugle Head with Phillips Drive: Self-countersinking eliminates secondary finishing; No.2 Phillips recess ensures positive bit engagement.
- Sharp Cut Point: Penetrates drywall and substrate with minimal force, reduces dust and surface damage.
- Case-hardened Carbon Steel: Core hardness ensures driving strength, surface hardness resists thread deformation.

Frequently Asked Questions (FAQ)
-
Q: Can these screws be used with any auto-feed screw gun?
A: Yes, the plastic strip design is universal and compatible with most major brands such as Senco, Paslode, Makita, Hitachi, and DeWalt. However, we recommend testing a sample strip with your specific tool before bulk purchase. -
Q: What lengths are available for this screw series?
A: We offer three standard lengths: 25mm (1 inch), 35mm (1-3/8 inch), and 40mm (1-9/16 inch). Custom lengths between 20mm and 50mm are available upon request, subject to minimum order quantity. -
Q: Are these screws suitable for metal studs?
A: Yes, the coarse thread can penetrate thin-gauge metal studs (0.5mm – 1.2mm) when pre-drilled or with self-drilling variants. For heavier steel, we recommend our fine-thread self-drilling screws (sold separately). -
Q: What is the corrosion resistance level of the yellow zinc coating?
A: The yellow zinc plating provides up to 72 hours of neutral salt spray protection (NSS) without red rust. This is suitable for indoor drywall applications. For outdoor or high-humidity environments, we suggest our hot-dip galvanized or stainless steel options. -
Q: How many screws come in a box?
A: Standard packaging contains 1,000 screws per box (in plastic strips of 60 each). We can also pack in bulk boxes of 5,000 or custom quantities to suit your project needs. -
Q: Do you provide free samples?
A: Yes, we offer free samples of up to 60 screws (one full strip) for evaluation. You only need to cover the shipping cost. Contact our sales team with your request. -
Q: What is the lead time for large orders?
A: For orders up to 500,000 pieces, typical production time is 20-30 days after confirmation and deposit. Rush orders can be arranged for an additional fee. -
Q: Can I get these screws with a different coating (e.g., black phosphate, zinc clear)?
A: Yes, alternative finishes such as black phosphate, clear zinc, or nickel-plating are available on request. Minimum order quantities and lead times may vary.
