Your advantages at a glance

3 embedment depths:

With up to 3 embedment depths, the UltraCut FBS II allows an optimal adaption to different applications / load requirements.

Expansion-free anchoring:

Expansion-free anchoring (undercut) allows for lowest edge- and axial spacings.

The assessment (ETA Option 1) :

The assessment (ETA Option 1) covers the use of singlepoint anchors in cracked and non-cracked concrete.

Performance categories seismic C1 and C2:

The performance categories seismic C1 and C2 ensure that the strictest of safety standards and earthquake specifications can be fulfilled.

Multiple use in temporary fixings:

The concrete screws are also approved for multiple use in temporary fixings (e.g. inclined supports) after a verification with the checking gauge FUP. Also with young concrete 10 N/mm2.

Drill holes do not need to be cleaned:

Drill holes do not need to be cleaned during vertical installation (ceiling and floor).

Approved adjustment :

The approved adjustment for the concrete screws allows the screw to be unscrewed twice for a total length of 20 mm, to place maximum 10 mm packing below the base plate head or to align the attached part, and then to tighten the screw again.

Product highlights

The unique saw tooth geometry allows a fast cutting into the Mounting base also for multiple use.
Thanks to the special thread geometry, the flanks cut themselves deep into the concrete and offer the highest loads. This saves costs, as fewer fixing points and smaller anchor plates are required.
The approval-compliant adjustment of the concrete screw allows the screw to be used twice for a total of 20 mm, max. 10 mm underlay or to remove the Align the attachment part and then tighten the screw again.
The UltraCut FBS II is available in two head versions: countersunk head and hexagon head. (with and without Torx drive).
The under-head riffling prevents the screw from being unintentionally loosened and creates so more security.

Reusability for temporary anchoring of construction site equipment

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.

UltraCut FBS II R – 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 R offers the possibility for use in masonry (solid construction material).
