- Individual fixing point: Normal weight concrete C20/25 to C50/60 (uncracked concrete)
- Anchors in a redundant non-structural system: Anchorage of non-load-bearing systems (M6-M16, cracked and uncracked concrete)
- Suitable for fastening threaded rods, metal structures, metal profiles, grilles, cable conduits, pipes, mounting rails etc.
- For use in concrete < C20/25 and pressure-resistant natural stone (without approval)
- W-ED/A4 (stainless steel A4) can be used in dry indoor areas, outdoors (including in industrial atmospheres and close to the sea) or in wet rooms, provided that no particularly aggressive conditions are present
- W-ED/HCR (HCR high corrosion-resistant steel) can be used in areas where there is a very high risk of corrosion (e.g. indoor swimming pool atmosphere, road tunnels, poorly ventilated car parks, or parts that are immersed in seawater or in coastal atmospheres)

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. Please refer to the European Technical Approval Guidelines (ETAG), Appendix C, for information on combining tensile and shear loads, the influence of the edge distance and groups of anchors. 2) The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. 3) The admissible loads were determined without axial influence and the influence of the edge distance. 4) Fire resistance rating: Drop-in anchor W-ED/A4 in conjunction with screws made of stainless steel A4. |
