· Frequently Asked Questions (FAQ)
Q: What is your minimum order quantity (MOQ)?
A: Our standard MOQ is 500 pieces for standard sizes. For custom or prototype orders, we offer low-volume production starting at 100 pieces to support your project development.
Q: What is the typical lead time for orders?
A: Standard orders are processed and shipped within 7–15 business days after payment confirmation. Custom or large-volume orders may require 15–30 business days, depending on complexity and quantity. Expedited production is available for urgent orders upon request.
Q: Can you customize these coupling nuts to my specifications?
A: Yes! We offer full customization, including custom thread sizes, lengths, hex dimensions, material grades, and surface finishes. Our engineering team can also help design custom fasteners to match your exact application requirements.
Q: Do you provide quality certifications?
A: All products are manufactured under ISO 9001 quality standards. We can provide material test reports (MTR), dimensional inspection reports, and compliance documents upon request.
Q: Are these nuts suitable for high-vibration applications?
A: Brass coupling nuts offer good resistance to loosening under normal vibration. For high-vibration environments, we recommend pairing them with thread locker or using lock washers to maintain secure connections.
