Washers for use in structural steelwork, product grade C, 8 mm thick at every size, with the hole and outside diameter of an ISO 7091 washer of the same size. The nominal dimensions are the same as DIN 7989-2; the two parts differ in tolerances and hardness, not in geometry. Together with DIN 7989-2 it replaced the 1974 edition of DIN 7989.
