Strong Undercut Anchor FSU.

The anchoring system for extreme safety and load requirements.

Strong Undercut Anchor FSU.

Product Highlights

  • 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.

Performance characteristics

Always on the safe side with FSU:

Approved for seismic applications of the performance categories C1 and C2.

Approval for sprinkler systems:

The FSU complies with the VdS CES guidelines for sprinkler systems,planning and installation when using the corresponding approval (ETA 22/0674).

Safe even in extreme situations:

Safety when it counts! Especially load-bearing steel constructions must not fail in the event of a fire. The FSU has proven its performance even under fireload. The ETA also allows dimensioning up to fire resistance class R 120.

Lasts for eternity

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.

NEW: DMC (DataMatrix-Code) on the anchor

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.


DMC in the fischer PRO app

Information, technical data, etc. can be viewed with the fischer PRO app both before and after installation.
To do this, navigate to the tile "Productscanner" and scan the DMC.
You will then see all the information about the scanned product. In the download area you can download the ETA and other data.

Designing can be so easy

The fischer design software FiXperience supports you as a planner, structural engineer and craftsman safely and reliably in the design of your projects. FiXperience has a modular structure and can be used for a wide range of applications.

The new, modular structure of the program includes engineering software and special application modules.
