fischer ULTRACUT FBS II 10 x 120 35/- US R hex head, A4 stainless steel concrete screw 
The high performance concrete screw made from A4 stainless steel for use where it's exposed the elements. Approved for outdoor use.
The fischer ULTRACUT FBS II US R Stainless steel concrete screws with specially hardened red tips are a versatile choice for a variety of applications. They are resistant to corrosion, making them ideal for use in wet rooms and external environments. The red tip also helps to provide a faster and more secure installation by cutting into the concrete more easily. Additionally, the approved adjustment feature allows the screw to be unscrewed twice to align the attached part, and then to be tightened again. This can be helpful for correcting mistakes during installation, or for adjusting the screw's position after it has been installed.
Specially hardened red tip: Faster and more secure installation.
A4 stainless steel concrete screw: Guarantees a high level of corrosion resistance especially for wet rooms and external applications.
Special saw tooth geometry: Enables fast cutting into the concrete.
Drill holes do not need to be cleaned during vertical installation (ceiling and floor): Fast installation (Note: For floor fixings the hole must be drilled 3x drill hole diameter deeper.)
ETA approval covers applications in cracked concrete and seismic power categories C1 and C2: Safe and approved.
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: Precision fixing.
Three embedment depths: Allows use in many different applications.
Short UltraCut FBS II R, with a reduced embedment in depth: Allows for a short drill hole depth, fast installation and less reinforcement hits.
