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.
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
Powerful and optimal for outdoor applications and wet rooms
The specially hardened red tip guarantees a noticeably faster and safer installation.
The concrete screw made of stainless steel ensures a high corrosion protection and allows the application in wet rooms and outdoors.
The ETA approval covers applications in cracked concrete, as well as the seismic performance categories C1 and C2.
The concrete screw ULTRACUT FBS II A4 offers the possibility for use in masonry (solid construction material).
