Fischer 543575 FBS II 12 x 70 10/-/- US A4 hexagon with U-ring 20 pieces

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 applications outdoors or in damp areas. 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 borehole cleaning is required for installation in ceilings and floors. The expansion-free anchoring (undercut) ensures very small centre-to-centre and edge distances .

Advantages

• The specially hardened red tip allows for faster and safer assembly
• The stainless steel concrete screw ensures a high degree of corrosion resistance, especially in wet areas and external applications
• The special geometry of the toothing allows fast screwing into concrete
• Drill holes need not be cleaned during vertical installation (ceiling and floor). For floor mounts, the hole must be drilled 3x drill hole diameter deeper
• ETA approval covers cracked concrete in seismic applications in categories C1 and C2
• The attachment can be unscrewed up to twice within the approval to insert a shim of up to 10 mm or to align the attached part and then retighten 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 a limited anchorage depth, allows for a short borehole depth, quick installation and less chance of hitting reinforcement.

Building Materials

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

Assembly

• The FBS II A4 is designed for push-through mounting
• Drill holes need not be cleaned in case of vertical mounting (ceiling and floor) or when using hollow drills. When mounting in floors, the drill hole should be drilled 3x dØ deeper
• An impact wrench fitted with black cap or TX bit is recommended for installation
• The concrete screw is correctly installed when the head is flush with the attachment and no more movement is visible (manual and visual check).
