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 4762 replaces DIN 912 | There is some similarity | Nominal range changed | Fine thread moved to ISO 12474.
