ZYKON Undercut Anchor for Secure Fixing in Cracked Concrete

The fischer ZYKON undercut anchor FZA is an anchor made from zinc-plated steel, stainless steel and highly corrosion-resistant steel. The undercut anchor is ideal for anchoring façades, railings and steel constructions in cracked concrete, both inside and outside. The undercut drill hole is created in a single work step with the special drill bit FZUB. The undercut anchor is set 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 undercut 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 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.
