Corrosion resistance:
M4, M5 approx. 240h/≥ M6 approx. 480h/≥ M10 approx. 720 hours of base metal corrosion according to DIN EN ISO 9227-NSS
The specified corrosion resistances apply for the corrosion tests according to DIN EN ISO 9227-NSS (salt spray mist testing), 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 mist test to real assembly and operating conditions is not possible in the majority of cases. When designing a connection, both the combined materials and any coatings and the environmental conditions during operation must be considered by the designer when selecting a suitable corrosion protection coating.
Working principle of locking ribs:
During tightening, the counter-material is "rolled" in the area of the bolt contact surface by the locking ribs. This causes a plastic deformation that hardens the surface. No significant settling is determined at the end of tightening. The locking ribs limit the amount of settling of the connection and therefore reduce the loss of pretensioning force.
