Product Q&A

Q:What international standards do you manufacture hex bolts to?

We produce hex bolts to all major global standards under one roof. This includes DIN 931/933, ISO 4014/4017, ANSI/ASME B18.2.1, BS 916, and JIS B1180. We offer both metric and inch series, covering UNC, UNF, and BSW threads. Custom prints are also welcome.

Q:Can you offer surface finishes that meet European automotive ELV and environmental regulations?

Absolutely. Our eco-friendly finishes are a standard offer. We provide trivalent chromium passivation (Cr3+) zinc plating that is fully ELV-, RoHS-, and REACH-compliant. For extreme corrosion protection, we offer zinc-nickel alloy plating (capable of 720+ hours to red rust in salt spray per ASTM B117) and Cr6-free Dacromet/Geomet coatings.

Q:Is your quality management system IATF 16949 certified for automotive production?

Yes, our manufacturing facility is IATF 16949 and ISO 9001 certified. Our entire quality assurance system, from incoming raw material inspection to final shipment, is designed to meet the sub-PPM (defective Parts Per Million) delivery requirements of automotive OEMs and Tier-1 suppliers. We are also ISO 14001 certified for environmental management.

Q:How do you handle quality complaints or a defective product issue?

We take every quality issue seriously with a structured problem-solving approach. Our team will issue an initial containment within 24 hours, followed by a formal 8D Corrective Action Report within 14 business days, which identifies the root cause and implements permanent corrective actions to prevent recurrence. Your trust and line-down prevention are our top priority.
