Fischer FBS II A4 Stainless Steel Concrete Screw
Fischer FBS II A4 is an A4 stainless steel high performance concrete screw for absolute installation ease in the exterior area.
Up to 3 embedment depths allows for the same screw to be used for different component thicknesses.
Expansion-free anchoring (undercut) allows for lowest edge- and axial spacings
The assessment ETA Option 1 covers the use of single point anchors in cracked and non-cracked concrete.
The performance categories seismic C1 and C2 ensure that the strictest of safety standards and earthquake specifications can be fulfilled.
The approved adjustment for the concrete screws allows the screw to be unscrewed twice for a total length of 20mm, to place maximum 10mm packaging below the base plate head or to align the attached part, and then to tighten the screw again.
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.
