DIN933 full thread hex Hexagon Head Bolts Grade8.8 carbon steel zinc plated surface

DIN (Deutsches Institut für Normung – German Institute for Standardization) standards are issued for a variety of components including industrial fasteners as Metric DIN 933 Hexagon Head Cap Screws / Bolts. The DIN standards remain common in Germany, Europe and globally even though the transition to ISO standards is taking place. DIN standards continue to be used for parts which do not have ISO equivalents or for which there is no need for standardization. IN this case the ISO equivalent for DIN 933 is ISO 4017.
