Specification

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 4017 replaces DIN 933 | There is some similarity | Nominal dimensions extended | Width across flats changed for M10, M12, M14 and M22.
