ZYKON undercut anchor FZA
The fixing system with the highest safety in cracked concrete
Steel girders
VERSIONS
▪ zinc-plated steel
▪ stainless steel
▪ highly corrosion-resistant steel
BUILDING MATERIALS
Approved for:
▪ Concrete C20/25 to C50/60,
cracked and non-cracked
Also suitable for:
▪ Concrete C12/15
▪ Natural stone with dense structure
Installations in tunnels
APPROVALS
High performance steel anchors
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.
▪ The ideal interaction of threaded bolts
and sleeve with FZA-D allows for a
high shear load and therefore fewer
fixing points.
APPLICATIONS
▪ Steel constructions
▪ Guard rails
▪ Consoles
▪ Step irons (FZA-ST)
▪ Ladders
▪ Cable conduits
▪ Machines
▪ Staircases
▪ Gates
▪ Façades
FUNCTIONING
▪ The FZA is suitable for pre-positioned
installation, whereas the FZA-D is suitable
for push-through 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.
