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.
