Are you asking about the screws to attache the base plate to the window frame?

For the base plate - the parts book shows - three required -  DIN 007982 004206 (B 4, 2X22 DIN 7982 DBL 8454) DIN 7982 = Sheet metal screw,  4.2 X 22 mm DBL 8454 - finish of galvanic chromium plated 

I was not able to find the meaning of the "B" in the DIN part listing - it appeared to be used for sheet metal screws, not machine type screws which would have "M" for metric. I am sure others will be able to decode that.
