Fischer Concrete Screw UltraCut FBS II US TX 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. 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. 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. Applications Guard rails Consoles/Base plates Metal profiles Shelving systems Protection barriers Results / beam anchors Temporary anchoring, e.g. of building site equipment Shuttering props Reinforcement of bridges Rehabilitation of old and ailing buildings Rehabilitation of car parks Building Materials Approved for: Concrete C20/25 to C50/60, cracked and non-cracked Reinforcement of existing concrete structures Bricks of clay (EN771-1) Solid sand-lime brick (EN771-2) Perforated sand-lime brick (EN771-2) Approved for: ETA-15/0352 ETA-20/0321 ETA-20/0134 DoP No. 0185 DoP No. 0227 DoP No. 0311 UKTA-0836-23/6750 Z-21.8-2049 Installation 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).
