I just head over to McMaster Carr's website and place a will call order when I need screws. Its probably where Tony gets his stuff from.
Talking like $10 for 100 m3 screws, so you spend a total of $15 and you've got a lifetime supply of them. Bash away to your hearts content knowing you'll always have whats needed inthe tool box.
Still, a good thing to have.

M3 stainless steel 318 screws in 20mm lenth, $7.80 for a pack of 100. They are located pretty close buy so I can just pick them up.
