Fischer FBS II Zinc Plated Concrete Screw Bolts have ETA (European technical assessment) that meets the NZBC requirements (NZS 3101 concrete structures standard).

• 50-year design life for internal use.
• Carbon steel with zinc plating
• ETA approval covers applications in cracked concrete and seismic power categories C1 and C2.
• Three embedment depths allowing use in many different applications and enable a high flexibility.
• The special saw tooth geometry enables fast cutting into the concrete.
• No drill hole cleaning is required for installation in ceilings and floors.
• The expansion-free anchorage (undercut) ensures low edge and axial spacings.
• The approved adjustment for the concrete screws allows the screw to be unscrewed twice to place maximum 10 mm packing below the base plate head or to align the attached part, and then to tighten the screw again.

Applications

• Guard rails
• Consoles/Base plates
• Metal profiles
• Steel constructions
• Façades
• Protection barriers

Approval

• ETA-15/0352
• ETA-20/0134
• DoP No. 0185
• DoP No. 0227

• The UltraCut FBS II is recommended for the push-through installation.
• Drill holes do not need to be cleaned during vertical installation (ceiling and floor). For floor fixings the hole must be drilled 3x drill hole diameter deeper.
• We recommend using a tangential impact screwdriver with a suitable impact screwdriver socket or an internal TX drive.
• The screw is installed correctly when the screw head sits flush on the fixture and cannot be screwed in deeper (visual setting control).
