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 ZFSHL is as follows:
- Diameter ≥ M6 - 480h*
- Diameter ≥ M10 - 720h*
- * Guideline values: No base metal corrosion at points without thread in salt spray mist testing 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 0.09μ - 0.14μ due to top coat with integrated lubricating particles
ISO EN 1664 replaces DIN 6927 | There is some limited similarity | Nuts with fine thread included in DIN EN 1667 | Nut height changed | Width across flats for size M10 changed from 15 mm to 16 mm.
