The fixing system with the highest safety in cracked concrete.

ZYKON undercut anchor FZA

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.

Advantages

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.

Functionality

The FZA is suitable for pre-positioned installation.
The undercut drill hole is created using the special FZUB drill.
Once the anchor has been placed in the drill hole, the expansion sleeve is driven over the cone using the FZE Plus setting tool, and the undercut drill hole is filled with a positive fit.
