Heavy duty Fischer concrete anchoring

Practical benefits

Fast cutting tooth geometry: The specialized saw tooth design cuts effortlessly into concrete, allowing you to secure heavy structural elements quickly.
Zero drill hole cleaning: You save valuable installation time because vertical floor and ceiling fixings require no bore hole cleaning.
Multiple embedment depth options: Different embedment depths allow you to adapt the screw easily for various fixture thicknesses up to 30 mm.

In a nutshell

The right choise for

With the Fischer fbs II 14X95 30/10/- us concrete screw, you create heavy-duty, dependable anchorages in solid concrete without the mess of chemical resins or separate plugs. The specialized saw tooth geometry cuts smoothly into concrete, allowing you to secure base plates, steel structures, and railings quickly. You save significant installation time during vertical drilling in floors and ceilings, as drill hole cleaning is not required. Offering versatile embedment depths for fixture thicknesses up to 30 mm, this hex-head screw adapts easily to your project needs. Furthermore, it can be loosened twice for precise component alignment, ensuring complete control and reliable structural fastening.

Product description

The high-performance concrete screw for absolute installation ease.

The fischer UltraCut FBS II is the perfect concrete screw for top installation comfort. The special saw tooth geometry enables fast cutting into the concrete. Drill hole cleaning is not required for installations in ceilings or floors. Thanks to the national approval, multiple usage for temporary anchorings (for example, formwork construction) is permitted. For the installation of the wall screw, we recommend a tangential impact driver with a compatible socket or a special TX bit. The concrete screw is ideal for the fixation of railings, protection barriers, cantilevers, and formwork bracings, for example.

With up to 3 embedment depths, it allows for the same screw to be used for different component thicknesses
The special saw tooth geometry enables fast cutting into the concrete
The approved adjustment for the concrete screws allows the screw to be unscrewed twice to align the attached part, and then to tighten the screw again
With up to 3 embedment depths, the UltraCut FBS II US allows for the same screw to be used for different component thicknesses
The special saw tooth geometry enables fast cutting into the concrete
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
Expansion-free anchoring (undercut) allows for lowest edge- and axial spacings
The ETA approval covers applications in cracked concrete and seismic power categories C1 and C2
The 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
The checking gauge allows for reuse in temporary fixings (e. g. inclined supports) covered by the national approval
The concrete screw FBS II 6-10 in zinc-plated steel, multiple-coated steel CP and stainless steel R has an ETA for bricks of clay (EN771-1), solid sand-lime brick (EN771-2) and perforated sand-lime brick (EN771-2) for a flexible use in different substrates
The installation of the concrete screw FBS II 6-10 in zinc-plated steel, multiple-coated steel and stainless steel R in masonry brick can be made in the joints or in plastered substrates also in groups

Suitable for

The UltraCut FBS II is recommended for the push-through installation
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
We recommend using a tangential impact screwdriver with a suitable impact screwdriver socket or an internal TX drive
The screw is installed correctly when the screw head sits flush on the fixture and cannot be screwed in deeper (visual setting control)
