  • E.g. for fastening pipes, ventilation ducts, cable clamps, suspensions with threaded rods, mounting rails, brackets, metal profiles, brackets for façade or ceiling substructures in pre-positioned installation

  • Fastenings subject to seismic activity in earthquake-prone areas (only concrete)

  • Fastenings subject to exposure to fire


W-BS/S (galvanised steel) may only be used in dry indoor room conditions

1) The partial safety factors of the resistances yM regulated in the evaluation/approval and a partial safety factor of the effects of γF = 1.4 have been taken into account. For a combination of tensile and shear loads, for the influence of the edge distance and anchor groups please see the appropriate guidelines e.g. DIN EN 1992-4.
2) The concrete has normal reinforcement. Higher values are possible for higher concrete strengths.
3) The admissible loads were determined without axial influence and the influence of the edge distance.
4) Number of attachment points ≥ 3 and at least one anchor per attachment point produces a load per attachment point of Fperm ≤ 1.4 kN or number of attachment points ≥ 4 and at least one anchor per attachment point produces a load per attachment point of Fperm ≤ 2.1 kN. The admissible loads can be increased if the design shows that the requirements governing the strength and rigidity of the component to be attached remain satisfied even after the failure of an anchor in terms of the limit state of serviceability and load-bearing capacity.
5) The assembly data must be observed.

Notes:
For further details on compressive strength, spacing, edge distances and installation positions, please refer to ETA-23/0196
To determine the admissible load, the partial safety factor from ETA γM=2.5 was taken into account on the resistance side and a partial safety factor γF=1.4 on the impact side.
The specified values apply to an individual anchor in masonry with fvko: 0.15 [N/mm²] and σd: 0.2 [N/mm²].
For combinations of tensile and shear loads, bending torques or reduced spacing and edge distances, please see ETA-23/0196.

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:
