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.

Application area

Individual fixing point with approval:


Normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete)



Especially suitable for fixtures in wooden construction applications in concrete:


  • Mounting of e.g. support beams, sleepers, inferior purlins, canopies, wooden substructures, etc.

  • Fastenings under seismic conditions in earthquake areas

  • Fastenings under exposure to fire


W-BS/S (galvanised steel) may only be used in dry indoor room conditions



For use in concrete < C20/25 and pressure-resistant natural stone (without approval)

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.
