Hex Socket Bolt

Welcome to the Hex Socket Bolts category at MJ Anchor (Hebei DuoJia Metal Products Co., Ltd.), your premier manufacturer and global supplier located in Handan Yongnian, the largest fastener production base in China. Drawing on the technical expertise of our predecessor, the Yonghong expansion screw factory, we produce a comprehensive range of hex socket head cap screws—including DIN 912 (Cylindrical Head), ISO 7380 (Button Head), and DIN 7991 (Flat Countersunk Head)—specifically engineered for applications requiring a smooth, streamlined finish and high torque capability. Our hex socket bolts are precision-manufactured to comply with rigorous international standards, including GB, DIN, ANSI, and BS, ensuring seamless integration into precision machinery, automotive assemblies, and high-end structural projects. Fabricated from high-grade Carbon Steel or Stainless Steel (SS304/SS316), these fasteners are available in specialized high-tensile strength grades, ranging from 8.8 and 10.4 to 12.9, to handle extreme mechanical stresses in confined spaces. To guarantee long-term durability and protection against environmental corrosion, our products feature professional surface treatments such as Black Oxide, Zinc Plating (Yellow/White), and Dacromet. With our advanced factory-direct production lines, we support custom manufacturing for non-standard thread pitches, specialized lengths, and unique head dimensions 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 engineering.
