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*
- * Guideline values: No base metal corrosion at points without thread in salt spray tests according to DIN EN ISO 9227 NSS.
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
ISO EN 1665 replaces DIN 6921 | There is some limited similarity | Some head heights changed | Flange diameter is unchanged | Widths across flats for M10, M12, M14 and M16, M20 changed | Strength 12.9 removed | Fine thread removed.
