Increased assembly productivity

When using fasteners with hexalobular recess (TX), the power is transmitted over a large surface area across the flanks of the recess rather than being centred on one point, as is the case with hexagon socket recesses. This has a number of advantages:

Reduced tool wear

Tool does not slip because power is distributed optimally

No damage to surface coat

No wobbling

Screw locates securely

Hexalobular internal driving features are standardised in accordance with DIN EN ISO 10664

As a result, fasteners with hexalobular recess are standardised and can be used all over the world.

Notice

The values given here have been calculated on the assumption of optimal conditions and without knowledge of the design context. The dispersion of the assembly tools and the dispersion of the friction coefficient were not explicitly taken into account. In the specific case, it is necessary to check the applicability of the information. This is the responsibility of the person who is responsible for design.

VDI 2230: Annex A; assumption of total friction coefficient = 0.12

VDI 2230: Assumption of torque-controlled tightening; friction coefficient class B; therefore assumption of tightening factor = 2

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 v

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).
