Female thread anchor with metric thread for economical anchoring in concrete, zinc-plated steel

Small drill hole depth

High load-bearing capacities

Visual setting check and hand protection when installing with the marking/expander tool

Mechanical setting tool makes installation quicker and easier

Immediate load-bearing capacity – no waiting

Attached part can easily be removed at any time

The attached part can be anchored with a fastening screw or a threaded rod

No installation torque required

The stop bit used with the attachable expander tool makes it quicker and easier to install. The matching drill holes make the installation even more secure.
