Bienvenue sur le Flange Bolts catégorie à 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. Leveraging the deep technical expertise of our predecessor, the Yonghong expansion screw factory, we produce a comprehensive range of hex flange bolts—notamment DIN 6921 et ANSI/ASME B18.2.1 standards—specifically engineered for superior load distribution and vibration resistance in automotive, machinery, and structural steel applications. Our flange bolts feature an integrated washer design that increases the bearing surface area, effectively eliminating the need for separate washers and reducing assembly time. Fabricated from high-grade Acier au carbone ou Acier inoxydable (SS304/SS316), these fasteners are offered in high-tensile strength grades including 8.8, 10.9, and 12.9 to handle extreme mechanical stresses. To guarantee long-term durability and protection against environmental corrosion, we provide professional surface treatments such as Galvanisation à chaud (HDG), Zingage jaune, Zingage blanc, et Dacromet. Grâce à nos chaînes de production de pointe, directement en usine, nous assurons fabrication sur mesure for non-standard head dimensions, serrated or non-serrated flanges, and specialized thread lengths based on your unique engineering blueprints. MJ Anchor is committed to providing reliable, laboratory-tested fastening components that satisfy the most demanding safety standards of modern global engineering.
