Zinc-flake coatings are chromium(VI)-free corrosion protection coatings for commercial vehicle construction, construction machines, agricultural vehicles and equipment, and all other fields that have vehicle construction standard corrosion protection requirements.
The corrosion resistance of ZFHSL is as follows:
- Diameter ≥ M6 - 480h*
- Diameter ≥ M10 - 720h*
The designation ZFSHL refers to the following corrosion coating:
- Zinc flake coating, with top coat, silver colour, with lubrication that alters the friction coefficient.
- Adjusted friction coefficient range from 0.09–0.14 μ due to top coat with integrated lubricating particles
DIN 933 has been withdrawn and replaced by ISO 4017. There is some similarity (nominal dimensions extended | width across flats changed for M10, M12, M14 and M22).
