· Frequently Asked Questions (FAQ)
Q: What is your minimum order quantity (MOQ)?
A: Our standard MOQ is 100 pieces for standard sizes. For custom or prototype orders, we offer low-volume production starting at 50 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 knobs/nuts to my specifications?
A: Yes! We offer full customization, including custom dimensions (diameter, height), thread sizes, knurl patterns, material grades, and surface finishes. Our engineering team can also help design custom knobs 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 knobs/nuts suitable for high-vibration applications?
A: The knurled design provides excellent grip for hand-tightening, and when paired with thread locker, they offer good resistance to loosening in moderate vibration environments. For high-vibration applications, we can recommend alternative materials or designs.
