Secure Fastening Under High Vibration Conditions
Vibration can cause conventional fasteners to loosen over time. We have been manufacturing high-strength fasteners since 2011 and have supplied critical components to Sany Heavy Industry, where equipment operates under severe vibration conditions.
This Automotive Threaded Fastener is designed for use in engines, chassis, and other automotive assemblies exposed to continuous vibration and road impact.
Manufactured from high-strength alloy steel with property grades 8.8, 10.9, and 12.9, it offers tensile strength up to 1200 MPa, ensuring stable and reliable fastening performance.
Precision Manufacturing – Backed by Data
Our facility is equipped with 17 heat treatment units and a fully automated production line, ensuring consistent mechanical properties.
Thread accuracy conforms to national standard 6H / 6g tolerances. Available sizes range from M6 to M24, with custom specifications available upon request.
Surface treatment options include zinc plating, Dacromet coating, and phosphate coating. Dacromet provides excellent corrosion resistance in harsh environments.
This product operates within a temperature range of -40°C to 150°C and complies with GB/T 3098.1 automotive fastener standards.

Versatile Fastening Solutions for Automotive Applications
We provide more than fasteners-we deliver reliable connection solutions for automotive systems.
This Automotive Threaded Fastener is available in standard, self-locking anti-loosening, and flange locking configurations. It can be used with spring washers or flat washers depending on application requirements.
It is widely applied in engine assemblies, suspension systems, gearboxes, chassis frames, and wheel hubs.
Manufactured from high-strength alloy steel or stainless steel, it meets automotive-grade performance standards. With over a decade of experience since 2011, we are committed to delivering fastening solutions that ensure long-term reliability.
