Fischer FBS II concrete screw hex head with flange A4

Fischer UltraCut FBS II A4 is a high-performance concrete screw that ensures excellent installation in outdoor conditions. The UltraCut FBS II US A4, with its specially hardened tip (red color), is a highly efficient anchoring solution for fast installation. The concrete screw with an integrated washer is ideal for damp areas. ETA approval for cracked and non-cracked concrete as well as seismic loads, and classification in fire resistance class R 120, ensure even greater safety. The saw-tooth geometry enables quick and easy installation. When installing in ceilings and floors, cleaning of the drill hole is not required. The expansion-free fastening ensures low edge distance and low spacing requirements.

• The specially hardened red tip provides faster and safer installation.
• The stainless concrete screw ensures high corrosion resistance, especially in damp areas and outdoor installations.
• The special serrated design enables fast bite into concrete.
• ETA approval covers performance categories C1 and C2 in cracked concrete and seismic applications.
• Drill hole cleaning is not required for horizontal installation (ceiling and floor) or when using a hollow drill bit.
