The undercut anchor for through-type installations in cracked concrete.
The fischer ZYKON push-through anchor FZA-D is an anchor made of zinc-plated 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 through-type 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 push-through anchor FZA-D is ideal for fixing steel constructions, railings, and machines within internal areas in cracked concrete.
