Fischer 543573 FBS II 10 x 100 15/- US A4 hexagon with U-ring 50 pcs.

Fischer 543573 FBS II 10 x 100 15/- US A4 hexagon with U-ring 50 pcs.

The Fischer concrete screw FBS II US A4, with the specially hardened red tip, is a powerful anchoring solution for quick installation. The concrete screw with the pressed-in washer is ideal for outdoor applications or in wet rooms. The European technical approval for cracked concrete and uncracked concrete as well as for seismic loads and classification in fire resistance class R 120 guarantees even more safety. The saw-tooth geometry allows for quick and easy installation. No cleaning of the drill hole is required for installation in ceilings and floors. The expansion-free anchoring (undercut) ensures very small spacing and edge-to-edge distances.

Benefits

• The specially hardened red tip allows for quicker and safer assembly
• The stainless steel concrete screw guarantees a high level of corrosion resistance, especially in wet areas and external applications
• 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
• 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 three anchoring depths allow the use of the FBS II A4 in many different applications with a high degree of flexibility
• The short FBS II A4, with its reduced anchoring depth, allows for short borehole depths, fast installation and reduced risk of hitting reinforcements

Building materials

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

Montage

• The FBS II A4 is designed for pass-through 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
• An impact wrench fitted with a black cap or TX bit is recommended for assembly
• The concrete screw is correctly mounted when the head is flush with the attachment and no movement is visible (manual and visual check)
