similar to DIN 933 | DIN standard has been withdrawn
ISO 4017 | steel | 8.8 | zinc-plated, thick-film passivated (VZD) | Cr(VI) - free | metric thread

Note: Similar to DIN 933 | DIN-standard has been withdrawn | changed spanner widths for M10, M12, M14 and M22

Surface (VZD): galvanized, thick-film passivated, min. 5µm | corrosion resistance to DIN EN ISO 9227*: white rust 72h, red rust 144h | defined coefficient of friction µ(total) = 0.12 - 0.18 for elements with a nominal tensile strength ≥ 800 MPa

*The verification of the mentioned minimum requirements is carried out according to the test conditions of DIN EN ISO 4042, galvanic coatings for fasteners. For dimensions < M5, the above values may deviate downwards.

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.
