fischer Zykon Undercut Anchor FZA
Undercut anchor for pre positioned (FZA bolt version and internally threaded anchor FZA-I) and push through installation (FZA-D bolt version). A cylindrical conical hole with an undercut is produced with the drill bit FZUB in one work process.
When setting the anchor, the anchor sleeve is driven over the cone with a hammer (or setting tool) and fills the undercut hole with a positive fit. Also available: special version FZA ST A4 for hot step irons according to DIN V 1211 GS / 1212 GS. Stainless steel version of the corrosion resistance class III, e.g. A4 for outdoor use and in damp conditions. Highly corrosion-resistant steel of the corrosion resistance clas IV, e.g. 1.4529 for applications in aggressive atmospheres.
