Fischer FBS II countersunk concrete screw SK-R 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 red tip, is a highly efficient anchoring solution for fast installation. The concrete screw with an integrated washer is ideal for damp environments. ETA approval for cracked and non-cracked concrete, as well as for seismic loads, and classification in fire resistance class R 120 provide even greater safety. The serrated geometry enables quick and easy installation. No drill hole cleaning is required when installing in ceilings and floors. The non-expanding fixing ensures low edge distances and short spacing.

Benefits:
• The specially hardened red tip provides faster and safer installation.
• The stainless concrete screw ensures high corrosion resistance, especially in damp environments and outdoor installations.
• The special serrated design enables fast biting into concrete.
• ETA approval covers performance categories C1 and C2 in cracked concrete and seismic applications.
• No drill hole cleaning is required for horizontal installation (ceiling and floor) or when using a hollow drill bit.
