ISO 7380-2 | Round head screws | with flange | steel | 10.9 | zinc-plated, thick-film passivated (VZD) | Hexalobular / Torx |Metric thread | Cr(VI) - free

Note:
• Due to their head geometry, these screws are limited in their load bearing capacity, see DIN EN ISO 898-1
• Some dimensions with thread to head

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.
