Packaging unit

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.

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

The Belleville washer form features angled teeth to create an optimum and simultaneous friction-fit and form-fit connection.


It makes sense in many cases—primarily when using short screws and loads which are vertical to the screw axis—to prevent the connection loosening by using lock washers to supplement the pre-tensioning force.
