Frequently Asked Questions
-
Q: What does “double countersunk” mean?
A: The double countersunk head has two angled surfaces, allowing the screw to sink flush or slightly below the material surface without extra pre-countersinking. This provides a neat finish and reduces splitting in thin panels. -
Q: Are these screws suitable for outdoor use?
A: Yes. The Ruspert coating offers excellent corrosion resistance (typical salt spray test over 500 hours), making them suitable for outdoor furniture, decking, and other exterior applications. However, for extreme marine environments, we recommend consulting our technical team for the best coating option. -
Q: What is C1022A material? Is it strong enough?
A: C1022A is a low-carbon steel commonly used in fastener manufacturing after case hardening. It achieves surface hardness of HRC 48-52, providing high torque resistance while maintaining a ductile core. This combination ensures the screw can handle high driving torque without snapping. -
Q: Can I get samples before placing a bulk order?
A: Absolutely. We offer free samples for standard sizes (shipping cost may apply). Please contact our sales team with your specific requirements, and we will arrange sample packs for evaluation. -
Q: What drive types are available?
A: Standard drive is Phillips (PH2 and PH3). Pozidriv and Torx drives are available upon request for certain sizes. Minimum order quantities may apply for non-standard drives. -
Q: What is the MOQ (minimum order quantity)?
A: The MOQ depends on the size and coating. For popular sizes (e.g., 4.0x40mm, 4.5x50mm), we can accept orders as small as 5,000 pieces. For less common sizes or custom orders, MOQ may be higher. Contact us for detailed information. -
Q: Do you provide custom packaging or labeling?
A: Yes. We offer private labeling and custom packaging (boxes, polybags, or bulk cartons with your brand). Please discuss your requirements with our sales team for costing and lead time. -
Q: How do you ensure quality consistency?
A: Each production batch undergoes dimensional inspection (head diameter, length, thread pitch), hardness testing, torque testing, and coating thickness checks. We follow internal quality procedures and can provide inspection reports upon request.
