Hi,
I can only tell you that for metric screws, there are screws which have a
pitch of 0.5mm, 0.75mm and 1mm. And for a 3mm screws I guess, the correct
pitch could be either 0.5 or 0.75mm which you need.
If you need, I could get 3mm screws for you from a local hardware store here
in Austria or Switzerland and mail them to you - but you might need to wait
a week or so to get them.
Cheers George Nyman
