    Terms & Conditions


    Manufactured from Zinc-plated steel, with a hex-flange head. Designed for use in applications such as channel systems, pipe routes, ventilation ducts, etc. Ultracut FBS has ETA Approval for cracked and non-cracked concrete as well as seismic loads, and classification in fire resistance class R 120. The UltraCut FBS II 6 US is perfectly designed for applications such as fixings of pipe routes, channel systems, ventilation ducts and facilities in the building service engineering. When the concrete screw is screwed into the drill hole using an impact driver, the thread flanks cut deep into the concrete, thus ensuring top load-bearing capacity. The low drilling effort saves time in the case of multiple fixations.

    Product Features

    • The first concrete screw with diameter 6 and variable embedment depths: High flexibility and a precise adaption on the loads.

    • ETA assessment option 1 includes the use in cracked and non-cracked concrete: Highest safety requirements.

    • First 6 mm diameter concrete screw with an ETA assessment for C1 seismic performance category for additional safety standards: Pioneering technology.

    • Approved for multiple use of non-load bearing systems: Ideal for the installation of pipe routes, cable trays and prestressed hollow concrete ceilings.

    • Drill holes do not need to be cleaned during vertical installation (ceiling and floor): Fast installation (Note: For floor fixings, the hole must be drilled 3x drill hole diameter deeper).

    • Different head designs available: Maximum application flexibility.

    • Hexagonal head with pressed washer and ribs under the head: Prevents accidental loosening of the anchor, making the system more secure.

    • Special head geometry for use in mounting rails with a socket (SW10): Simple installation of the add-on part.

    • Approved adjustment for the concrete screws allows the screw to be unscrewed twice to place maximum 10 mm packing below the base plate head or to align the attached part, and then to tighten the screw again: Precision fixing.

    • For use in masonry (solid building material): Versatile anchoring.

    • Pipeline routes

    • Suspension for individual pipes

    • Suspended mounting rails

    • Prestressed concrete hollow core ceilings

    • Cable trays

    • Ventilation ducts

    • Perforated tapes

    Approved for:

    • Concrete C20/25 to C50/60, cracked and non-cracked

    • Prestressed hollow concrete ceilings C30/37 to C50/60 for the multiple use of non-load bearing systems

    Also suitable for:

    • Concrete C12/15

    • Masonry with a dense structure

    • Solid building materials

    Installation instructions


    • The UltraCut FBS II 6 is recommended for the push-through and pre-positioned installation.

    • We recommend using a tangential impact screwdriver with a suitable impact screwdriver socket or an internal TX drive.

    • Drill holes do not need to be cleaned during vertical installation (ceiling and floor). For floor fixings the hole must be drilled 3x drill hole diameter deeper.

    • The screw is installed correctly when the screw head sits flush on the fixture and cannot be screwed in deeper (visual setting control).
