ISO 7380-2, steel 010.9, zinc-plated, thick-film passivated (ZSML)

Fasteners with zinc-plated chromium(VI)-free thick-film passivation (ZSML) offer a future-proof alternative compared to surfaces containing chromium(VI). The coating consists of a zinc layer with passivation on a (chrome III) basis and sealing coat (top coat with integrated lubricating particles).



Overview of advantages:



  • Higher quality replacement for common zinc-plated coatings such as A2C or A3C

  • Adjusted friction coefficient range from 0.09 μ-0.14 μ due to top coat with integrated lubricating particles

  • Thermal capacity up to 120°C

  • Even coating distribution

  • Functional and decorative
Notice

Due to their head geometry, these screws can only be subjected to limited loads, see DIN EN ISO 898-1
