self tapping screws

Welcome to the Self-Tapping Screws category at MJ Anchor (Hebei DuoJia Metal Products Co., Ltd.), your premier manufacturer and global supplier located in Handan Yongnian, China’s largest fastener hub. Building on the technical heritage of the former Yonghong expansion screw factory, we produce a comprehensive range of self-tapping screws—including DIN 7981 (Pan Head), DIN 7982 (Countersunk), and DIN 7504 (Self-Drilling) standards—specifically engineered for high-efficiency fastening in sheet metal, plastic, and timber. Our screws are precision-manufactured from case-hardened Carbon Steel or Stainless Steel (SS304/SS316) to ensure superior thread engagement and pull-out resistance. We offer diverse drive types such as Phillips, Slotted, and Torx, along with professional surface treatments like Blue/White/Yellow Zinc Plating and Dacromet for exceptional corrosion protection. With our advanced factory-direct production lines, we support custom manufacturing for non-standard lengths and specialized head styles based on your engineering blueprints. MJ Anchor is committed to delivering laboratory-tested components that meet the rigorous safety demands of modern construction and industrial assembly.
