Fischer 536867 Concrete screw FBS II 10 x 230 175/165/145 US hexagon with U-ring 20 pcs.

Fischer 536867 Concrete screw FBS II 10 x 230 175/165/145 US hexagon with U-ring 20 pcs.

The Fischer FBS II is the concrete screw for optimum ease of installation. The special tooth geometry allows a fast setting in concrete. When mounted in the ceiling or floor, the drill hole does not need to be cleaned. Thanks to national approval, multiple use in temporary anchorages, e.g. for formwork work, is no problem. A tangential head screwdriver with a bit suitable for the impact screwdriver or a special TX bit is recommended for mounting the wall bolt. The concrete screw is ideal for securing handrails, impact protection, consoles or formwork, for example.

Benefits

• With up to 3 anchoring depths, the FBS II US allows the same screw to be used for different attachment depths
• The special geometry of the teeth allows fast screwing into the concrete
• Drill holes do not need to be cleaned during vertical installation (ceiling and floor). For floor fixing, the hole must be drilled 3 times deeper than the hole diameter
• Spread-free anchoring (undercut) ensures smallest centre-to-centre and edge-to-edge distances
• The ETA approval relates to cracked concrete in seismic applications in categories C1 and C2
• The attachment can be unscrewed up to two times within the approval to fit a shim of up to 10 mm or to align the attached part and then re-tighten the screw
• The control sleeve allows re-use with temporary fixings (e.g. braces) that fall under the DIBt approval

Building materials

• Concrete C20/25 to C50/60, cracked and uncracked
• Concrete C12/15
• Solid building materials
• High density masonry

Montage

• The FBS II is suitable for through hole mounting
• Drill holes need not be cleaned in the case of vertical installation (ceiling and floor) or when using hollow drills. In case of floor mounting, the drill hole should be drilled 3 x dØ deeper
• A tangential impact screwdriver with a bit suitable for the impact screwdriver or a special TX bit is recommended for assembly
• If the screw head is in contact with the mounting piece, the screw has been mounted correctly (visual check of the mounting)
