IATF16949 certified
Standard & custom fastener solutions
Comprehensive supply chain
We utilize proprietary long bolt cold-heading technology, enabling one-step cold extrusion for non-standard and special-shaped parts—replacing traditional hot forging. This ensures stable dimensions, better appearance, streamlined processes, and lower costs, delivering both quality and value.
With advanced equipment covering raw material processing (pickling, wire drawing) to finished products, our automated lines support an annual output of 10,000 tons. We respond quickly and deliver reliably for both standard bulk orders and non-standard customizations.
Certified to IATF 16949, we implement full-process quality management. Equipped with projectors, metallographic testers, and hardness testers, we strictly monitor every step, from incoming materials to final products, ensuring compliance with international and automotive industry standards.
Our dedicated R&D team excels in producing standard bolts (GB, DIN, etc.) and specializes in custom non-standard bolts and special-shaped parts per drawings or samples. We offer one-stop solutions from design and tooling development to mass production, addressing diverse application challenges with professional technical support.
