MBN 10105, steel, strength class 10.9, from M12 with fine thread. Silver zinc-flake coating in accordance with DBL 9440.40 (shape C ≙ partial thread)

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)

Notice

Flange head screws reduce the risk of pretension loss caused by setting of contact surfaces. The surface pressure generated under the screw head during tightening is low compared to conventional hexagon heads (without flange), as the force is distributed over a larger contact surface.



Advantage:


  • Less setting required due to fewer parts to be connected compared to connections using washers.

  • The concave washer pressing against the contact surface increases the elasticity of the connection so that the setting/creeping movements that occur are counteracted and pretension loss is generally prevented
