Custom Fasteners

Welcome to the Custom Fasteners category at MJ Anchor (Hebei DuoJia Metal Products Co., Ltd.), your premier technical manufacturer and global supplier located in Handan Yongnian, China’s largest fastener production hub. Drawing on the extensive engineering heritage of our predecessor, the Yonghong expansion screw factory, we specialize in producing high-performance customized fastening solutions—including non-standard bolts, specialized nuts, unique washers, and complex threaded components—specifically engineered for the unique structural requirements of heavy industry, automotive, and renewable energy sectors. Our custom components are precision-manufactured using advanced cold-heading, hot-forging, and CNC machining processes to meet or exceed rigorous international standards, including DIN, ANSI, ISO, and GB. Fabricated from high-grade Carbon Steel (Grades 8.8, 10.9, 12.9) or Stainless Steel (SS304/SS316), our products ensure maximum reliability under extreme mechanical loads and vibration. To guarantee exceptional service life, we offer professional surface treatments such as Hot-Dip Galvanization (HDG), Dacromet, and Zinc Plating. With our robust factory-direct production lines, we provide comprehensive custom manufacturing based on your specific technical drawings or samples, supporting both rapid prototyping and large-scale wholesale demands. MJ Anchor is committed to providing reliable, laboratory-tested fastening components that meet the safety and precision demands of modern global infrastructure.
