Packaging unit

The box quantity defines the number of articles in one package.

Structure of our article number

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

Information on product price

Depending on your account price settings, the displayed price can be per BOX or per PU.

Surface protection


In accordance with DBL 9440.40 (silver-coloured zinc flake coating with lubrication integrated in seal, Cr(VI)-free) > VDA 235 – 104.42



Corrosion resistance


  • ≤ M8 - approx. 480 hrs, no base metal corrosion acc. to DIN EN ISO 9227 – NSS

  • ≥ M10 - approx. 720 hrs, no base metal corrosion acc. 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 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 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 hexagonal 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 adjustment required due to there being fewer parts to be connected compared to connections using washers.
