Screws for My Big Muff

[b to g is yummy]

I appear to have lost the screws for the cover of my big muff. Anyone know where I could get more, or even just the screw size? (I painted it pink, I don't really want to walk into the hardware store, umm..got anything that'll fit in here?!)

I also lost the battery cover in the process...getting sick of having duct tape holding stuff together but I don't wanna spend a wack of dough on a few tiny parts.

Thanks in advance for any input!

They're small machine screws. Sorry, you'll need to bring the case into the hardware store to get it right.
