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

Notice

Head dimensions in ISO 14581 countersunk screws are gauged in accordance with ISO 7721

Some screws with short dimensions are threaded up to the head, see ISO 14581

Countersinks for screw heads in accordance with ISO 14581 must comply with ISO 15065
