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 4035 replaces DIN 439-2 (with chamfer) | There is some similarity |Strength class for stainless steels changed from 50 to 025 and from 70 to 035 | Width across flats changed for M10, M12, M14, M22 | Nominal diameter for M1.8 removed | ISO 4035 only governs standard thread | Fine thread was moved to ISO 8675.
