similar to ISO 4014 | DIN standard has been withdrawn
Art.no.: 9318.8FZ2065
DIN 931 | steel | 8.8 | hot-dip galvanised (thermally galvanised) | Cr(VI) - free | metric thread | screws can be paired with a 6h tolerance-compliant female thread
Note: Similar to ISO 4014 | DIN-standard has been withdrawn | changed spanner widths for M10, M12, M14 and M22
Hot-dip galvanised screws have very good resistance against corrosion. The zinc layer is much thicker than with galvanic coatings
This standard specifies the characteristics of hexagon head bolts of product grade A and B:
Product grade A = For threads M1,6 to M24 and nominal lengths = 10d or 150 mm, whichever is the shorter
Product grade B = For threads over M24 or nominal lengths > 10d or 150 mm, whichever is the shorter.
Information about the product class can be found in the technical details of the selected article.
