Specification

ISO 7380-2, steel, strength class 10.9, zinc-flake coating, silver (ZFSHL)

Zinc-flake coatings are chrome-(VI)-free corrosion protection coatings for commercial vehicle assembly, construction machinery, agricultural vehicles and equipment, and all other areas that have corrosion protection requirements at vehicle construction level.

Corrosion resistance for ZFSHL is:

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 friction value adjusted lubrication.

Adjusted friction coefficient range from 0.09μ – 0.14μ due to top coat with integrated lubricating particles

Notice

Due to their head geometry, these screws can only be subjected to limited loads, see DIN EN ISO 898-1
