The mechanical properties are regulated in SAE J429

The thread length is based on ASME B18.2.1

1 inch (in) = 25.4 mm

Standard thread tolerance in accordance with ASME B1.1 = 2A (for external thread)

Zinc-flake coatings are chromium (VI)-free corrosion protection coatings for commercial vehicle construction, construction machines, agricultural vehicles and equipment and all other fields that have vehicle construction standard corrosion protection requirements.

Corrosion resistance for ZFSHR:

Diameter ≥ M6 - 480 h*

Diameter ≥ M10 - 720 h*

* Reference values: No base metal corrosion in areas without thread in salt spray tests according to DIN EN ISO 9227 NSS.

The designation ZFSHR 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 0.12-0.18 μ due to top coat with integrated lubricating particles
