Optimum load bearing values thanks to matched screw geometry.
Application and approval
For safety-relevant applications in combination with fischer aircrete anchor GB in aerated concrete
Aerated concrete with compressive strength 2 to 4 N/mm²
Aerated concrete wall or ceiling boards with compressive strength 3.3 to 4.4 N/mm²
You can find detailed information on building materials in the registration document.
The safety screw guarantees approved safety in combination with the fischer aircrete anchor GB. The anchor is pressed into the aerated concrete as the screw rotates. The anchor holds by creating a form fit.
