Product Overview
These chipboard screws feature a Pozi drive (Pozidriv) for enhanced torque transfer and reduced cam-out, paired with a half-thread design that optimizes grip in chipboard and wood while minimizing splitting. The Ruspert coating is a multi-layer anti-corrosion treatment that outperforms standard zinc plating, making them suitable for indoor and outdoor applications. With full sizes available from small diameters to large lengths, these screws meet diverse assembly requirements.
Key Features & Benefits
- Rustproof Ruspert Coating – Passes 1,000+ hours salt spray test (data available upon request), ideal for humid or outdoor environments.
- High Hardness C1022A Steel – Core hardness of HV 400-500 ensures the screw penetrates tough materials without snapping or twisting.
- Pozi Drive Design – Provides better driver engagement than Phillips, reducing bit wear and installation torque.
- Half Thread Configuration – Threads near the tip pull material together; smooth shank prevents over-tightening and wood splitting.
- Full Size Range – Available in diameters from 3.0mm to 6.0mm and lengths from 12mm to 100mm (custom sizes on request).
- No Snapping Guarantee – Optimized heat treatment process minimizes brittleness for reliable performance.
- Factory Direct Pricing – Eliminate middleman costs, ideal for bulk buyers and OEM projects.

Why Choose Our Pozi Chipboard Screws?
Compared to ordinary chipboard screws, our product stands out due to the Ruspert coating – a proprietary anti-rust treatment that offers superior longevity in damp conditions. The high hardness of C1022A ensures that even when fastening dense particleboard or engineered wood, the screw maintains integrity without fracturing. Additionally, the half-thread design reduces the risk of stripping, and the Pozi drive allows for faster installation with lower operator fatigue.
For bulk purchasers, our factory-direct model means you get consistent quality at competitive prices. We offer full-size availability with short lead times (15–30 days depending on order volume). Every batch is tested for hardness, coating adhesion, and torque performance to meet international standards requested by our clients.

Frequently Asked Questions
-
Q: What sizes are available for these Pozi chipboard screws?
A: We offer full sizes from 3.0mm×12mm up to 6.0mm×100mm. Custom lengths and diameters can be produced with a minimum order quantity. Please contact us with your specific requirements. -
Q: Is the Ruspert coating truly rustproof for outdoor use?
A: Yes. The Ruspert coating provides excellent corrosion resistance, typically passing 1,000+ hours in a neutral salt spray test (NSS) per ASTM B117. It is suitable for outdoor applications such as decking, fencing, and garden furniture. For extreme marine environments, we recommend additional protection; test results can be shared upon request. -
Q: Do these screws come with a Pozi bit included?
A: Generally, screws are sold without bits. However, we can include matching Pozi bits in bulk packaging if arranged in advance. Standard Pozi bits (PZ1, PZ2, PZ3) are widely available from tool suppliers. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is 500 kg (approximately 50 cartons). For non-standard custom sizes, MOQ may be higher. Small trial orders (e.g., 10 kg) can be arranged for sample evaluation – please inquire. -
Q: Can you provide samples before bulk purchase?
A: Yes, we offer free samples for existing stock sizes, but the buyer covers shipping cost. Custom samples require a small sample fee, refundable upon first bulk order. -
Q: How do these screws compare to stainless steel screws?
A: While stainless steel offers excellent corrosion resistance, our C1022A with Ruspert coating provides similar rust protection at a lower cost, plus higher hardness (HV 400–500 vs. typical SS304 hardness of HV 150–200). For applications where magnetic properties are needed, our screws are magnetic; stainless steel is not. -
Q: What is the delivery time for a standard order?
A: For standard sizes and quantities, production takes 15–20 working days after deposit. Larger orders (over 5 tons) may require 25–30 days. We can also arrange expedited shipping if needed. -
Q: Do you have any quality certifications?
A: We follow internal quality control standards for hardness, coating thickness, and torque. Specific certifications such as ISO or CE can be provided if required by your market; please ask our sales team for details.
