Thanks, but it is not that easy.
There are different screws to the head and front cover
The head screws are 2.85 mm. (and not possibly 7/64)
An M3 does not fit
The front cover are 3.4 mm (3.5mm?) Not possibly 9/64
I haven't tried with a M 3.5 because I haven't any yet.

If I had a thread pitch gauge I would have the answer.
I take my screws and go to the bolt and nut store!!
