Highest loads and efficient installation. Ideal for fastening metal structures, zinc-plated steel

For anchorage in concrete and masonry

Extremely flexible application thanks to up to three effective anchorage depths (size 6-14)

Fastening can be adjusted up to two times after installation (size 6-14), for example in order to align railings or anchor plates (please refer to the installation instructions)

Very high loads

Very low spacing and edge distances thanks to very low expansion effect

¹⁾ The partial safety factors of the resistances y_Mregulated in the evaluation/approval and a partial safety factor of the effects of γ_F = 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 compressive strengths. ³⁾The permissible loads were determined without axial and edge distance influence. ⁴⁾ Number of attachment points ≥ 3 and at least one anchor per attachment point produces a load per attachment point of F_adm≤ 1.4 kN or number of attachment points ≥ 4 and at least one anchor per attachment point produces a load per attachment point of F_adm≤ 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 γ_M=2.5 was taken into account on the resistance side and a partial safety factor γ_F=1.4 on the impact side. The specified values apply to an individual anchor in masonry with f_vko: 0.15 [N/mm²] and σ_d: 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.
