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
Hexagonal nuts complying with DIN 934 cannot support test loads as per DIN EN ISO 898-2.
- The strength class designation has two vertical bars added before and after the strength code to differentiate.
DIN 934 has been withdrawn and replaced by ISO 4032/8673. There is no similarity (nominal Ø changed | Some nut heights changed | Width across flats changed for M10, M12, M14, M22 | ISO 4032 for standard thread | ISO 8673 for fine thread).
