DIN 6916 refers to a specific standard established by the Deutsches Institut für Normung (DIN), which is the German national organization for standardization. This standard delineates the specifications for high-strength structural washers that are intended for use in steel structures. These washers are designed to distribute the load under bolt heads or nuts, preventing damage to the part being secured and ensuring a more reliable and even clamping force. The DIN 6916 standard specifically addresses the dimensions, material properties, and other key characteristics necessary for these washers to perform effectively in high-stress applications. By adhering to this standard, manufacturers and engineers can ensure that their constructions meet the rigorous requirements necessary for safety and longevity in structural applications.
