Specification

ISO 4014, steel 12.9, zinc flake, silver (ZFSHL)

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*

* 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

Notice

ISO 4014 replaces DIN 931 | There is some similarity | Nominal size extended | Width across flats for M10, M12, M14 and M22 changed.
