Understand the benefits of the Fischer FBS II High performance concrete screw


With up to 3 embedment depths, the ULTRACUT FBS II 

makes it possible for the same screw to be used for 

different component thicknesses. 

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 ensures that the strictest of safety standards and earthquake specifications can be fulfilled. 

The checking gauge allows multiple use covered by the approval. 

Through the special thread geometry, the screw flanks cut deeply into the concrete and allow higher loads. This saves costs because less anchor points and smaller base plates are required

The ULTRACUT FBS II is available in different head designs. Countersunk and hexagonal head with and without internal torx drive

Unique patented saw-tooth geometry cuts quickly into the concrete. It can be installed several times and used in reinforced concrete.

The approved adjustment allows the screw to be unscrewed twice for a total length of 20 mm, to place maximum 10 mm packing below the base plate head or to align the attached part, and then to tighten the screw again

The short ULTRACUT FBS II, with a reduced embedment depth, allows for a short drill hole depth, fast installation and less reinforcement hits which makes it an efficient choice for many applications.

The ribs under the head prevent accidental loosening of the anchor making the system more secure.

The checking gauge, available separately, allows the outer diameter of the thread to be checked prior to the screw being reused; this complies with the approval for multiple use
