- Positive-locking, removable anchorage with no expansion pressure
- Load-bearing function is retained, even under thermal load
- Tested fire resistance duration of 120 minutes
- Time saving – no anchor necessary
- Short installation times, as no tools are required for insertion
- AW drive for longer bit service life, improved power transmission and no ejection forces
- Through-hole mounting
- Immediate load-bearing capacity – no waiting after insertion
- Positive locking for high load-bearing capacity
- Removable
- Virtually no expansion forces on insertion
It is important to check that the components are correctly installed for the specific construction conditions (e.g. weight of window casement, surface properties, hole pattern in the brick). Fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4 may only be attached with the AMO Combi screw if appropriate individual approval has been obtained before installation starts.

Guidelines for planning and executing the installation of windows and exterior doors, 2020 edition
Art. no. 5995000000:
The fixture must safely transfer all standard forces affecting the window to the structure and the foundation. The total load must therefore be calculated from e.g. the window load, wind load and working load (see DIN 1055). The currently applicable building regulations stipulate that buildings and their components must be planned in such a way that they do not endanger human life and health or pose a risk to public safety. Attachment of the windows must also comply with this criterion.
When securing window walls compliant with the former DIN 18056 standard or elements with a surface area in excess of 9 m2 and fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4, the following must be observed
The DIN 18056 standard applied to window walls with a minimum surface area of 9 m² and a minimum side length of 2 m on the shortest side. Anchors with general or European technical approval or with individual approval should be used for this application. Similarly, only anchors with a general construction permit or European Technical Approval or with individual approval must be used to attach fall-proof glazing as specified in the German technical rules for safety glazing (TRAV) or DIN 18008-4.
