Flange Nut

Welcome to the Flange 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 technical expertise of our predecessor, the Yonghong expansion screw factory, we produce a comprehensive range of hex flange nuts—including DIN 6923, EN 1661, and ANSI/ASME B18.2.2 standards—specifically engineered for superior load distribution and structural stability. Our flange nuts feature an integrated wide flange that acts as a built-in washer, effectively increasing the bearing surface area and eliminating the need for separate components during assembly. We offer both Serrated Flange Nuts for maximum anti-vibration grip and non-serrated versions for specialized surface requirements. Precision-manufactured to comply with rigorous international standards, including GB, DIN, ANSI, and BS, these fasteners are essential for automotive, solar racking, and heavy machinery applications. Fabricated from high-grade Carbon Steel or Stainless Steel (SS304/SS316), they are available in various strength grades, ranging from Class 8 to Class 10 and 12, to handle extreme mechanical stresses. To guarantee long-term durability and protection against environmental corrosion, our products feature professional surface treatments such as Yellow Zinc Plating, White Zinc Plating, Hot-Dip Galvanization (HDG), and Dacromet. With our advanced factory-direct production lines, we support custom manufacturing for non-standard thread pitches, specialized flange diameters, and unique material specifications based on your specific engineering blueprints. MJ Anchor is committed to providing reliable, laboratory-tested fastening components that meet the safety and precision demands of modern global infrastructure.
