The system consists of stainless steel for optimum safety in cracked concrete.

Art.-No. 60778
Top Features
  • Maximum safety due to a positive fit connection.
  • Low axial and edge distances due to expansion pressure-free installation.
  • Fast installation, no exchanging tools. This saves time and costs.
  • Power-saving installation with low setting energy.
  • ETA approval for cracked concrete and fire resistance class R 120.

Product Description

The fischer ZYKON bolt anchor FZA is an anchor made of stainless steel. The special drill bit FZUB is used to create the undercut drill hole in a single work step. The undercut anchor is set in the pre-positioned installation. The expansion sleeve is driven above the cone with the setting tool FZE Plus and fills the undercut drill hole with a positive fit. The fischer ZYKON bolt anchor FZA is ideal for fixing façades, railings, and steel constructions within external areas in cracked concrete.
  • 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 distances and axial spacing, and thereby enables flexible use.
  • The FZUB special drill allows for a fast installation by creating the undercut without having to change tools.
  • The drill hole geometry allows for a very low setting energy, thus reducing the energy required for installation.
