Hefei SENOTECH New Materials Co., Ltd proudly presents our premium Yellow Zinc Plated Pozi Drive Chipboard Screws, specifically engineered for efficient furniture assembly. Since our establishment in 2020, we have committed to delivering high-quality fasteners that meet the rigorous demands of global markets. With an annual export value of US$1 million to US$1.5 million, we serve customers across North America, South America, Europe, Asia, Africa, and Oceania. Our chipboard screws combine advanced manufacturing techniques with strict quality control, ensuring reliable performance and long-lasting durability.
These screws feature a yellow zinc plated finish that provides excellent corrosion resistance, making them suitable for both indoor furniture and slightly humid environments. The Pozi drive design offers superior torque transfer and reduces cam-out, allowing faster and more secure installation. Each screw is hardened and heat-treated to achieve high torque strength, preventing breakage during assembly. Available in a full range of sizes, these screws accommodate various furniture thicknesses and materials, from particle board to MDF and solid wood.
Key Features & Technical Specifications
- Material: High-quality carbon steel (C1022A or equivalent) for optimal hardness and flexibility.
- Surface Treatment: Yellow zinc plating (passivated) per ASTM B633, offering 72+ hours salt spray resistance.
- Drive Type: Pozi (PZ) recess for increased driving torque and reduced bit slipping.
- Thread Design: Sharper, deeper threads with a 45° flank angle for faster insertion and better holding power in chipboard.
- Head Type: Countersunk flat head with nibs (or serrated underhead) for countersinking flush without splitting the material.
- Hardness: Surface hardness 450–550 HV, core hardness 320–400 HV – ensures strength without brittleness.
- Torque Resistance: Tested to withstand > 12 N·m for M5 diameter (varies by size) – suitable for power tool driving.
- Sizes Offered: Diameters from 3.5 mm (No.6) to 6.0 mm (No.14), lengths from 12 mm to 100 mm – full inventory available.

Advantages for Furniture Assembly
- High Torque Capacity: Our unique heat treatment process raises torque values by 30% compared to standard chipboard screws, reducing the risk of snapping during high-speed power driving.
- Pozi Drive Efficiency: The cross-shaped recess with deeper, angled slots engages more bit surface area, minimizing cam-out and worker fatigue – ideal for assembly lines.
- Anti-Corrosion Protection: Yellow zinc plating passes 72-hour neutral salt spray testing (NSS) without red rust, ensuring the screws remain rust-free even in humid storage or light outdoor furniture.
- Precision Threading: Sharp partial threads start easily and cut cleanly into chipboard, reducing the need for pre-drilling in many applications. Full threads available for paneling or hardwoods.
- Consistent Quality: Every batch is sampled for hardness, torque, and plating thickness before shipment. We provide a Certificate of Conformance (CoC) upon request.

Frequently Asked Questions (FAQ)
-
Q: What sizes of chipboard screws do you stock?
A: We offer diameters from 3.5 mm to 6.0 mm (No.6–No.14) and lengths from 12 mm to 100 mm. Full size list is available in our catalog; custom lengths are possible with MOQ. -
Q: Are these screws suitable for outdoor furniture?
A: Yellow zinc plating provides good corrosion resistance for occasional outdoor use, but for prolonged exposure we recommend stainless steel or black-coated options, which we can supply upon request. -
Q: Can I use a Phillips driver instead of Pozi?
A: Pozi drivers are recommended for optimal torque and to avoid cam-out. Pozi bits work well with our screws; standard Phillips bits can be used but may slip more easily. -
Q: Do you offer pre-drilling required?
A: Our partial thread screws are designed to self-start in chipboard and MDF without pre-drilling for most applications. For very dense materials or thin panels, pre-drilling may improve results. -
Q: What is the minimum order quantity (MOQ)?
A: For stock sizes, MOQ is 1000 pieces per size. For mixed sizes, we accept 5000 pieces total. Small trial orders are welcome for sample evaluation. -
Q: How are the screws packaged?
A: Standard packaging is in 1 kg or 5 kg boxes, or 25 kg bulk cartons. Retail clamshell packs with clear labeling are available for hardware store distribution. -
Q: Do you provide any certifications or test reports?
A: Yes, we can provide RoHS and REACH compliance reports, as well as third-party hardness and torque test results upon request. ISO certification is available from our manufacturing partners. -
Q: What is the typical lead time?
A: For standard stock sizes, lead time is 10-15 working days after order confirmation. For custom production (e.g., special length or finish), allow 20-30 days.
