Hex Nut

Welcome to the Hex Nuts category at MJ Anchor (Hebei DuoJia Metal Products Co., Ltd.), your premier manufacturer and global supplier located in Handan Yongnian, the heart of China’s fastener production industry. Drawing on the deep technical expertise of our predecessor, the Yonghong expansion screw factory, we produce a comprehensive range of hexagonal nuts—including DIN 934, ISO 4032, and ANSI/ASME B18.2.2 standards—specifically engineered for superior clamping force and structural integrity. Our hex nuts are precision-manufactured to comply with rigorous international standards, including GB, DIN, ANSI, and BS, ensuring seamless compatibility with high-tensile bolts and threaded rods in global construction and machinery projects. Fabricated from high-grade Carbon Steel or Stainless Steel (SS304/SS316), these fasteners are available in various strength grades, ranging from Class 4 and 8 to 10 and 12, to handle demanding mechanical loads and high-torque applications. To guarantee long-term durability and protection against environmental corrosion, our products feature professional surface treatments such as Hot-Dip Galvanization (HDG), Yellow Zinc Plating, White Zinc Plating, and Black Oxide. With our advanced factory-direct production lines, we support custom manufacturing for non-standard thread pitches (fine and extra-fine), specialized thicknesses (thin nuts/DIN 439), and unique material specifications based on your specific technical drawings. MJ Anchor is committed to providing reliable, laboratory-tested fastening components that meet the safety and precision demands of modern global infrastructure.
