The specialised saw tooth geometry provides:
- Quick and deep cutting into the concrete.
- Optimal multiple use
The thread geometry and the core diameter build a basis for high loads in concrete
Underhead ribs prevent an unintentional loosening
Different head shapes for a wide range of applications
Reusability for temporary anchoring of construction site equipment
The FBS II Ø 8-14 can be used for temporary fixings due to official approvals (ETA) (e.g. installation of formwork construction). Therefore, the thread diameter has to be checked with a test sleeve before any further installations.
As long as the screw end doesn't poke out over the test sleeve, the FBS II can still be used.
Up three screw-in depths
Using the example: FBS II 10x100 45/35/15 US
Tension load in dependency to the screw-in depth
= low load 4,29 kN and 45 mm useable length
= middle load 5,71 kN and 35 mm useable length
= high load 9,61 kN and 15 mm useable length
Metal construction - Railing anchorage
For maximum loads and minimum axial- and edge spacing in cracked concrete, in dry interior space.
