Specification

Increase in assembly productivity

When elements are joined using hexalobular (TX) fasteners, the force is transmitted over a large surface area across the flanks of the drive rather than being centred on one point, as is the case with hexagon socket drives, for example. This has a number of advantages:

Reduced tool wear

Tool does not slip because force is distributed optimally

No damage to surface coating

No wobbling

Screw locates securely

Hexalobular drives must comply with DIN EN ISO 10664

As a result, connection elements with hexalobular heads are standardised and can be used all over the world

Notice

Head dimensions in ISO 14581 countersunk screws are gauged in accordance with ISO 7721

Some screws with short dimensions are threaded up to the head, see ISO 14581

Countersinks for screw heads in accordance with ISO 14581 must comply with ISO 15065

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

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.
