Connection elements with galvanised chrome (VI)-free thick-film passivation (ZSML) offer a future-proof alternative compared to surfaces containing chrome(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 of common galvanised 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 layer distribution

  • Functional and decorative

Notice

ISO 7047 replaces DIN 966 | There is some limited similarity | Some head heights and head diameters have been changed | Thread lengths changed | Strength class 5.8 and 8.8 omitted | Recessed head penetration depths changed.
