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.
Documentation for block removal must also be provided.

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.

The packaging unit indicates the number of pieces/meters/kilos contained in the packaging. In the catalog section you can choose from the different packaging units when a selection menu appears.

If you do not know the packaging unit when entering the item number directly in the shopping cart or when registering with Easy-/VarioScan, you can simply leave the box empty. A packaging unit is automatically determined here.
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

Price per packaging unit (PU):
The displayed price always corresponds to the displayed packaging, For example, A PU of 250 pcs means the price for 250 pcs. A PU of 300 pcs means the price for 300 pcs. A PU of 10 m means the price for 10 metres.

Price with price code display (PSL):
The price always applies to a quantity that is arranged via a price code:
/1pc means price for 1piece
/100 pcs means price for 100 pieces
/10 m means price for 10 meters
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).
