Installation-friendly safety screw with countersunk head.
Optimum load bearing values thanks to matched screw geometry.
The fischer safety screw with countersunk head is produced from zinc-plated steel. The screw geometry is precisely matched to the fischer frame fixings SXR, SXRL, DuoXpand, and Aircrete anchor GB. When driving in the screw, the plastic sleeve of the anchor presses against the drill hole wall and expands in the building material.
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 approval 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.
