The UltraCut 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.
The fischer concrete screws FBS II 6-10 offer the innovative possibility for the ETA compliant application in masonry. This grants high security not only in concrete but also in many other applications in other substrates.
