Fischer 536881 Concrete screw FBS II 8 x 80 30/15 SK countersunk head 50 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

• High degree of flexibility in terms of load and thickness of the mounting parts due to up to two approved screw-in depths
• The special tooth geometry enables fast setting in concrete
• Drill holes do not need to be cleaned when fitting in ceilings or floors or when using hollow drills with extraction
• The spreader-free anchoring (rear cutting) allows for low edge and axis distances
• The ETA approval covers the application in cracked concrete as well as seismic performance categories C1 and C2
• The approval compliant adjustment allows the concrete screw to be loosened 2x, placed slightly below the mounting piece and/or aligned

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)
