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

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.
The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076
Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
