For fastening windows in concrete and solid block masonry. Particularly small cylinder head for screwing into narrow window rebates. Zinc-plated steel, blue passivated, RW 25 drive
  • 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
Notice

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.

Instructions

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.

The packaging unit indicates the number of pieces/meters/kilos contained in the packaging. In the catalog section you can choose from the different packaging units when a selection menu appears.

If you do not know the packaging unit when entering the item number directly in the shopping cart or when registering with Easy-/VarioScan, you can simply leave the box empty. A packaging unit is automatically determined here.
The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:

Price per packaging unit (PU):
The displayed price always corresponds to the displayed packaging, For example, A PU of 250 pcs means the price for 250 pcs. A PU of 300 pcs means the price for 300 pcs. A PU of 10 m means the price for 10 metres.

Price with price code display (PSL):
The price always applies to a quantity that is arranged via a price code:
/1pc means price for 1piece
/100 pcs means price for 100 pieces
/10 m means price for 10 meters
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
