ZYKON undercut anchor FZA-Q

The fixing system with the highest safety in cracked concrete

The fischer ZYKON undercut anchor FZA-Q is made from hot-dip galvanised steel. The easy-to-install undercut anchor is ideal for anchoring façade sub-structures, for example. The undercut anchor is set into the drill hole created with the stop drill FZBB in a pre-positioned and push-through installation. With the setting tool FZE Plus, the expansion sleeve is pressed over the cone and fills the drill hole in a positive-locking manner. This ensures top safety even for large crack widths. The European Technical Approval and classification into fire resistance class R 120 ensure added safety.

  • The special ZYKON undercut technology allows for a positive fit connection, and ensures maximum safety, even in large cracks.
  • The almost expansion-free installation of the anchor allows small edge clearances and axial spacings, and therefore flexible use.
  • The stop drill FZBB enables a predefined drill hole depth and a fast installation process.
