Mechanical Anchors – 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 man hole step irons according to DIN V 1211 GS / 1212 GS.
- A4 stainless steel version for outdoor use and in damp conditions, highly corrosion-resistant steel C (material no. 1.4529) for applications in aggressive atmospheres.
