Frequently Asked Questions
Do your fasteners meet automotive industry standards?
Yes. All our automotive fasteners are manufactured under IATF 16949 certified quality system. We can provide PPAP documentation, material mill certificates, and full traceability for all production batches to meet OEM and Tier-1 supplier requirements.
Can you guarantee the tolerance stability for mass production?
Absolutely. We maintain ±0.005mm tolerance consistency across all production runs using our 5-axis CNC equipment and 100% CMM inspection process. Our zero-defect manufacturing system ensures every part meets your specification, from prototype to mass production.
What materials do you offer for harsh environments?
We offer 316L stainless steel for coastal and high-corrosion environments, which provides superior chloride corrosion resistance. For high-temperature and high-stress applications, we recommend 17-4PH stainless steel, which offers excellent strength and fatigue resistance up to 400°C.
Do you support small batch orders and long-term supply?
Yes. We support the full product lifecycle, from prototype (1-5pcs) to small batch production (100-500pcs) and mass production (10,000+pcs). We can provide long-term stable supply for your ongoing projects, with consistent quality and lead time.
What is your lead time for custom orders?
Sample orders take 3-7 days. Standard production orders take 15-25 days, depending on complexity and quantity. For urgent orders, we offer expedited production service to meet your tight project deadlines.
What is the minimum order quantity?
We have no strict MOQ. For testing purposes, we accept sample orders as low as 1-5pcs. For production orders, the minimum is 100pcs, but we can discuss flexible terms based on your specific needs.
