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 4032 replaces DIN 934 | There is no similarity | Nominal diameter changed | Some nut heights changed | Width across flats changed for M10, M12, M14, M22 | Only for standard thread | Fine thread moved to ISO 8673.
