1. DIN 6916, a standard published by the Deutsches Institut für Normung, outlines the specifications for structural washers made from unalloyed steel with a large outer diameter. These washers are designed to distribute the load of a fastener over a larger surface area, thus preventing damage to the connected materials. Adhering to DIN 6916 ensures that the washers meet strict requirements for dimensions, material composition, and mechanical properties. Contractors and engineers rely on this standard to guarantee the safety and integrity of their construction projects, as using the correct type and size of washer is paramount in preventing structural failures.
