Zinc flake coatings are chrome (VI)-free corrosion protection coatings for commercial vehicle construction, construction machines, agricultural vehicles and equipment, and all other fields that require 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 0.09μ - 0.14μ due to top coat with integrated lubricating particles
ISO 4017 replaces DIN 933 | Standards are equivalent | Nominal dimensions extended | Width across flats changed for M10, M12, M14 and M22.
The dip-spin process typical of zinc-flake coatings can have a negative effect on the trueness to gauge in the case of small threads. For this reason, it is possible to ensure the screwability of size M5 threads, but not trueness to gauge.
