Female thread anchor with metric thread for economical anchoring in concrete, zinc-plated steel
  • Small drill hole depth

  • High load-bearing capacities

  • Visual setting check and hand protection when installing with the marking/expander tool

  • Mechanical setting tool makes installation quicker and easier

  • Immediate load-bearing capacity – no waiting

  • Attached part can easily be removed at any time

  • The attached part can be anchored with a fastening screw or a threaded rod

  • No installation torque required

  • The stop bit used with the attachable expander tool makes it quicker and easier to install. The matching drill holes make the installation even more secure.
Proof of Performance
  • ETA-02/0044 for individual fixing point, option 7, uncracked concrete

  • ETA-05/0120 for anchors in a redundant non-structural system, uncracked and cracked concrete, M6-M16

  • Fire resistance: F30, F60, F90 and F120; exposure to fire according to DIN 4102-2:1977-09 (UTTC - uniform temperature time curve)

  • Fire resistance: R30, R60, R90 and R120; TR020 (included in ETA-05/0120)

1) The partial safety factors of the resistances regulated in the approval and a partial safety factor of the actions of γF = 1.4 have been taken into account. For information on combining tensile and shear loads, on the influence of the edge distance, and on anchor groups, please refer to the European Technical Approval Guidelines (ETAG), Annex C.
2) The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths.
3) Steel quality 5.6. With a higher steel quality, higher shear load values apply.
4) The admissible loads have been determined without the influence of the axis and edge distances and apply to screws with steel quality ≥ 5.6.
5) Steel quality 5.6. With a higher steel quality, higher admissible bending moments apply.
6) Fire resistance rating: Drop-in anchor W-ED/S in conjunction with screws of strength classes ≥ 5.6.
7) Without approval.
8) Only for use in statically indeterminate systems and dry indoor areas.
9) Number of attachment points ≥ 3 and at least 1 anchor per attachment point results in a load per attachment point of Fadm ≤ 1.4 kN or number of attachment points ≥ 4 and at least 1 anchor per attachment point results in a load per attachment point of Fadm ≤ 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.

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
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB

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).
