DIN 6912 | steel | 08.8 | zinc-plated | Cr(VI) - free | metric thread
Note:Due to their head geometry, these screws are limited in their load bearing capacity, see DIN EN ISO 898-1
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 high-strength screws (≥ 8.8)
>*The verification of the mentioned minimum requirements is carried out according to the test conditions of ISO/CD 4042:2016, galvanic coatings for fasteners. For dimensions < M5, the above values may deviate downwards.
