Set Bolt

Welcome to the Set Bolts 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 set bolts—including fully threaded hex bolts (DIN 933) and socket set screws (DIN 913/914/916)—specifically engineered for applications requiring a secure, flush fit or high-torque clamping in machinery and structural assemblies. Our set bolts are precision-manufactured to comply with rigorous international standards, including GB, DIN, ANSI, and BS, ensuring seamless compatibility with global mechanical engineering blueprints. Fabricated from high-grade Carbon Steel or Stainless Steel (SS304/SS316), these fasteners are available in various strength grades, ranging from 4.8 and 8.8 up to 12.9, to handle demanding load-bearing and tensioning requirements. To guarantee long-term durability and protection against environmental corrosion, our products feature professional surface treatments such as Black Oxide, White Zinc Plating, Yellow Zinc Plating, and Hot-Dip Galvanization (HDG). With our advanced factory-direct production lines, we support custom manufacturing for non-standard thread pitches, specialized point styles (cup, cone, or flat), 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 infrastructure.
