The anchoring system with internal thread for top safety in cracked concrete.

ZYKON undercut anchor FZA-I

The fischer ZYKON internal threaded anchor FZA-I is made from zinc-plated and stainless steel. The metric internal thread allows for the use of conventional screws or threaded rods. The plug construction also enables surface-flush removal. 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 installation. With the setting tool FZE Plus, the expansion sleeve is pushed 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.
