Flat Washer

Welcome to the Flat Washers 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 flat washers—including DIN 125 (Standard), DIN 9021 (Large Outer Diameter/Fender), and ISO 7089 standards—specifically engineered to provide a smooth bearing surface and distribute fastener loads across a wider area. Our flat washers are precision-manufactured to comply with rigorous international standards, including GB, DIN, ANSI, and BS, ensuring seamless compatibility with high-tensile bolts and nuts in global construction, automotive, and machinery projects. Fabricated from high-grade Carbon Steel, Spring Steel, or Stainless Steel (SS304/SS316), these essential components are available in various hardness levels and thicknesses to prevent surface deformation and ensure structural integrity. To guarantee long-term durability and protection against environmental corrosion, our products feature professional surface treatments such as Hot-Dip Galvanization (HDG), Yellow Zinc Plating, White Zinc Plating, and Black Oxide. With our advanced factory-direct production lines, we support custom manufacturing for non-standard outer diameters (OD), specialized inner clearances (ID), 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.
