Welcome to Hefei SENOTECH New Materials Co., Ltd, a dynamic trading company established in 2020 with a strong focus on exporting high-quality fasteners. Our factory-direct chipboard screws, featuring a premium Ruspert coating and PZ drive, are designed to deliver reliable performance without snapping during installation. With full size availability and a commitment to consistent quality, these screws are an excellent choice for woodworking, furniture assembly, and construction projects across diverse markets including North America, Europe, South America, and Asia.
Our chipboard screws are engineered to meet the demands of both professional contractors and DIY enthusiasts. The combination of a hardened carbon steel core, advanced Ruspert anti-corrosion coating, and a precise PZ drive system ensures maximum holding power, reduced cam-out, and long-term durability. We offer a complete range of sizes, from short 12mm screws for thin panels to long 100mm+ screws for heavy-duty applications, all available for immediate shipment.
Key Features & Benefits
- Ruspert Coating: Provides superior corrosion resistance compared to standard zinc plating, ideal for humid or outdoor environments. The coating is also environmentally friendly.
- PZ Drive (Pozidriv): The cross-shaped drive with extra depth reduces slip and allows higher torque transmission, making installation faster and more efficient.
- No Snapping Design: Specially heat-treated and tempered to minimize brittleness, ensuring screws drive smoothly without breaking even into dense materials.
- Sharp Point & Aggressive Thread: Self-tapping thread design cuts quickly into chipboard, plywood, and MDF, reducing pre-drilling needs.
- Countersunk Head: Flush finish for a clean, professional look; suitable for use with screw caps or plugs.
- Full Size Availability: From #6 to #14 (or metric sizes 3.0mm to 6.0mm) in various lengths, we can supply exactly what your project requires.
- Factory Direct Pricing: Eliminate middlemen and enjoy competitive wholesale prices with consistent quality control.

Frequently Asked Questions (FAQ)
-
Q1: What is the difference between PZ and PH (Phillips) drive?
A: PZ (Pozidriv) has an additional cross slot indicating a more complex profile that reduces cam-out. It is commonly used in European markets and works best with PZ bits. PH (Phillips) can also be used but may not provide the same torque transfer. -
Q2: Can these screws be used for outdoor applications?
A: Yes, the Ruspert coating provides enhanced corrosion resistance compared to standard zinc plating. However, for extreme marine or chemical environments, we recommend consulting with our team for alternative coatings. -
Q3: Are full sizes available including unusual lengths?
A: Yes, we offer a comprehensive range from 12mm to 150mm (or more upon request) in both metric and imperial dimensions. Contact us for a complete size chart. -
Q4: Do I need to pre-drill before using these screws?
A: In most chipboard and softwood applications, the self-tapping design eliminates the need for pre-drilling. For very hard materials or dense MDF, pilot holes may improve performance. -
Q5: What packaging options do you offer?
A: We supply in bulk (cartons, pallets), retail boxes, or custom poly bags with your branding. Minimum order quantities vary by packaging type. -
Q6: How can I get a sample before placing a bulk order?
A: We offer free samples of up to 10 pieces for different sizes (buyer pays shipping). Please contact our sales team with your address and requirements. -
Q7: Do you have stock for immediate shipment?
A: Yes, we maintain a large inventory of common sizes (3.5x25mm, 4.0x40mm, 4.5x50mm, etc.) for fast delivery. Lead time for custom sizes is typically 15-20 days. -
Q8: What is the minimum order quantity (MOQ)?
A: MOQ is generally 1000 pieces per size for standard items. For mixed sizes, minimum total quantity is 50,000 pieces. We can discuss flexible terms for new customers.
