Surface protection:
In accordance with DBL 9440.40 (silver zinc-flake coating with lubrication integrated in sealing, Cr(VI)-free) > VDA 235-104.42
Corrosion resistance:
- ≤ M8 - approx. 480 h, no base metal corrosion in accordance with DIN EN ISO 9227-NSS
- ≥ M10 - approx. 720 h, no base metal corrosion in accordance with DIN EN ISO 9227-NSS
The specified corrosion resistances apply for the corrosion tests according to DIN EN ISO 9227-NSS (salt spray tests), at the earliest 24 h after coating in the "as coated" state, i.e. before sorting, packaging, transporting and/or assembly. These values can be reduced through inevitable handling and assembly processes.
A transfer of the corrosion resistances from the salt spray test to real assembly and operating conditions is not possible in the majority of cases. When designing a connection both the combined materials and if necessary coatings as well as the environmental conditions during operation must be considered by the designer in the selection of a suitable corrosion protection coating.
Friction coefficient:
μtot = 0.09-0.14 (VDA 235-101)
Flange nuts reduce the risk of pretensioning force loss when placed on the contact surfaces. When tightening, the resulting surface pressure under the nut is low compared to conventional hexagon nuts (without flange), as the force is distributed over a larger contact surface. The nuts are fitted with a clamping lock and therefore cannot be reused.
Advantage: Less setting required due to fewer parts to be connected compared to connections using washers.
