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
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

Self-tapping screws form a nut thread in cast blind holes, rim holes and drilled, lasered and punched sheet metal parts. Unlike thread cutting, self-tapping does not interrupt the material structure in the receiving thread. Instead, the material is displaced and strain-hardened.



Benefits:



Cost savings


  • Eliminates thread cutting


Non-cutting thread formation



Low rolling torques with greater thread flank overlap


  • TRILOBULAR shape of the core diameter combined with the radius profile of the thread flanks


High clamping force


  • Due to low rolling torques


High load-bearing capacity


  • Due to large thread flank overlap

  • Due to strain-hardened counter thread (nut thread)


Protection against loss (reduced likelihood of screw working loose)


  • Play-free and self-locking thread seating


The formed thread corresponds to a standard metric thread


  • Where necessary, the GEFU screw can be replaced with a metric screw.
Notice

The suitability of the GEFU for the application or component in question must be determined through preliminary testing. Guideline values for suitable hole diameters are specified in DIN 7500-2.
