Connection elements with galvanised chromium (VI)-free zinc thick-film passivation (VZD) offer a future-proof alternative to surfaces containing chromium (VI). The coating consists of a zinc layer with passivation on a chromium (III) basis.
Overview of advantages:
- Chromium (VI)-free alternative to A2C or A3C
- Thermal capacity up to 120°C
- Even coat distribution
DIN 931 has been withdrawn and replaced by ISO 4014. There is some similarity (nominal dimensions extended | Widths across flats changed for M10, M12, M14 and M22).
