I found myself scouring ebay and the likes for stainless metric flat head screws. There has to be a place that is used to dealing by the thousand count, or pound quantity per type and isnt marking up like crazy.

I know some of the big players like enco etc

And local players like Ace, Menards, Home Depot..

But does anyone have a "secret stash", some place where you can order a decent small shop quantity and have had good luck? (The internet is a big place)

For example, I was placing an order at amazon for some misc items, and stumbled upon 500 stainless m 3.0-.5 flat heads for like five bucks (free shipment). I checked other sizes and they were all much more. I ordered a couple packs-we will see if it gets filled.
