Zinc-flake coatings are chrome-(VI)-free corrosion protection coatings for commercial vehicle assembly, construction machinery, agricultural vehicles and equipment, and all other areas that have corrosion protection requirements at vehicle construction level.
Corrosion resistance for ZFSHL is:
- Diameter ≥ M6 - 480h*
- Diameter ≥ M10 - 720h*
The designation ZFSHL refers to the following corrosion coating:
- Zinc-flake coating, with top coat, silver colour, with friction value adjusted lubrication.
- Adjusted friction coefficient range from 0.09μ – 0.14μ due to top coat with integrated lubricating particles
ISO 7047 replaces DIN 966 | There is some limited similarity | Some head heights and head diameters have been changed | Thread lengths changed | Strength class 5.8 and 8.8 omitted | Recessed head penetration depths changed.
