Hex Socket Screw

Welcome to the Hex Socket Screws 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 socket head screws—including DIN 912 (Cylindrical Head), DIN 7991 (Countersunk), ISO 7380 (Button Head), and DIN 916 (Set Screws)—specifically engineered for high-torque transmission and space-constrained assemblies. Precision-manufactured to comply with rigorous international standards including GB, DIN, ANSI, and ISO, our hex socket screws are essential for machinery, automotive, and aerospace engineering. Fabricated from high-grade Carbon Steel in strength grades 8.8, 10.9, and 12.9, or Stainless Steel (SS304/SS316), they offer superior tensile strength and fatigue resistance. To guarantee long-term durability, we provide professional surface treatments such as Black Oxide, Zinc Plating, and Dacromet. With our advanced factory-direct production lines, we support custom manufacturing for non-standard thread pitches 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.
