. The short brass fixing PA 4 only requires a very low anchorage depth and is therefore the solution for thin board building materials.
. The special surface structure of the PA 4 prevents the fixing from rotating in the drill hole. This provides increased installation safety.
. The internal thread allows for the use of standard metric screws and enables the ideal adaptation to suit the intended use.
The PA 4 is suitable for prepositioned installation
Turning in the metric screw causes the front part of the brass fixing to expand, thus securely anchoring it in the substrate
Calculating screw length for flush fixing installation: Fixing length + fixture thickness = min screw length
