High Tensile Fastener Black grade 8.8 Hex Bolt DIN933/931

Short Description:

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.

Surface treatment and thread tolerance: DIN933 hexagon bolts are generally metric (coarse) and fine pitch, with mm millimeters as the unit of measurement. DIN933 coarse thread tolerance is: 6g, the coating is mainly boiled black, electroplating (blue and white zinc, yellow color zinc), non-electrolytic zinc powder coating (GEO). The tolerance matching before coating is mainly 6g/6H, and the tolerance zone matching after galvanizing can be changed to 6h/6G. However, after coating, it is affected by the thickness of the surface coating. When the thread is inspected by the corresponding tolerance, it is also There may be situations where it cannot be matched, and only nuts with matching specifications can be tested.
