Thanks to the national approval, multiple usage for temporary anchorings (for example, formwork construction) is permitted. For the installation of the wall screw, we recommend a tangential impact driver with a compatible socket or a special TX bit. The concrete screw is ideal for the fixation of railings, protection barriers, cantilevers, and formwork bracings, for example.

Top Features

• With up to 3 embedment depths, it allows for the same screw to be used for different component thicknesses.
• The special saw tooth geometry enables fast cutting into the concrete.
• The approved adjustment for the concrete screws allows the screw to be unscrewed twice to align the attached part, and then to tighten the screw again.

Advantages

• Maximum flexibility with regard to load and fixture thickness due to up to two approved embedment depths.
• The special saw tooth geometry enables fast cutting into the concrete.
• No drill hole cleaning is required for installation in ceilings or floors, or use of hollow drills with suction.
• The expansion-free anchorage (undercut) ensures really low edge and axial clearances.
• The ETA approval covers applications in cracked concrete and seismic power categories C1 and C2.
• Approval-compliant adjustment allows the concrete screw to be undone twice and the fixture to be underlaid or adjusted.
• The national approval allows multiple usage for temporary anchorings (for example, formwork construction).
