Highest load capacities and efficient mounting. Ideal for mounting wood structures (large washer as per DIN 440) in concrete, zinc-plated steel

Extremely flexible to use due to three anchoring depths

Fastening can be adjusted up to twice after installation, for example in order to align railings or anchor plates (please refer to the assembly guide)

Very high loads

Smallest spacing and edge distance thanks to very low expansion effect

Very fast and easy assembly and immediately load-bearing

Proof of Performance

European Technical Assessment ETA-16/0043 for individual fixing point, option 1, cracked and uncracked concrete:

Static and quasi-static effects

Seismic exposure, performance categories C1 and C2

Fire resistance R30, R60, R90, R120

DIBt National technical approval/general type approval Z-21.1-2075 as bonded screw anchor for anchoring in concrete

Use in combination with injection mortar WIT-BS as bonded screw anchor WIT-BS

In reinforced and non-reinforced and cracked and uncracked concrete C20/25 to C50/60

Notice

From size 8, we recommend the use of a suitable tangential impact screwdriver for installation. The recommended maximum nominal torque must be observed.

Application area

Wooden structures

Adjustment - subsequent aligning possible.

¹⁾ The partial safety factors of the resistances y_M regulated 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 strengths.
