Alright, here goes:
I wanted to get rid of most/all of the philips head screws and replace them with button-head stainless from McMaster and I don't have any means of finding the pitch?
>Would anyone know the pitch of Tamiya's hardware?
>And is M3 what I'm looking for?
(Tamiya has the sizes posted as like a 3x18mm)
>Would you rec. steel/black or Stainless?
Thanks for the help!!!

I don't want to place an order for 600 pcs. and be wrong!!
