Specification

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

Notice

ISO 4017 replaces DIN 933 | There is some similarity | Nominal dimensions extended | Width across flats changed for M10, M12, M14 and M22.
