The fischer ZYKON push-through anchor FZA-D 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 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 façades, railings, and steel constructions within external areas in cracked concrete.
