Böllhoff 40148.8VZD20160, Sechskantschrauben (Verpackung 10 Stk.)

Art.no.: 40148.8VZD20160
ISO 4014 steel 8.8 zinc-plated, thick-film passivated (VZD) Cr(VI) - free metric thread
Note: Similar to DIN 931 DIN-standard has been withdrawn changed spanner widths for M10, M12, M14 and M22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.
Information about the product class can be found in the technical details of the selected article.
