      The anchoring system for extreme safety and load requirements.

      Strong Undercut Anchor FSU-P

      The fischer strong undercut anchor FSU-P is a self-cutting undercut anchor made of galvanised and stainless steel for applications where highest loads and safety are required (e.g. heavy steel plant construction, nuclear power plants, oil & gas industry). The undercut anchor is ideal for heavy duty fixings to anchor steel structures, heavy piping and industrial machinery indoors and outdoors in cracked and non-cracked concrete. The FSU-P is set in push-through installation with the FSU-ST setting tool in a drilled hole created with the stop drill FSU-SD. The anchor cuts itself the undercut, creating a positive connection. This ensures maximum safety even with large crack widths in seismic areas. With the disassembly tool FSU-DT, the anchor can be removed quickly and completely.

      Advantages
      • The perfect form fit in the undercut guarantees the absorption of high loads (head bolt theory) for applications with the highest level of safety.
      • Six robust cutting teeth and the principle of self-undercutting enable precise and powerful setting in the concrete and thus simple and fast installation.
      • The plastic element of the FSU prevents the anchor from falling out of the drill hole and allows easy and safe overhead installation.
      • The low spreading forces of the FSU allow small edge and axial distances and offer maximum flexibility in all applications.
      • The setting depth markings on the anchor and setting tool (FSU-ST) ensure a quick visual installation check and provide additional safety and installation convenience.
      • The DMC (DataMatrix-Code) for unique identification and readout of product data on the anchor offers the possibility for flexible and exact data transparency and storage before and after installation. The code can be scanned using the fischer PRO app.
      • The ETA rating confirms a service life of 100 years. The FSU will last a whole century and is therefore perfect for large, long-lasting construction projects.
