Where can you buy those tiny screws that are used to mount flanges on lens boards?

I bought a lifetime supply (bag of 100) on Ebay.

They have just about every small screw or bolt you could possibly need.
The larger Ace HArdwares have good assortments also.

American Integrated Supply
They don't have their own website, but they sell via eBay, I get all the brass wood screws and some machine screws that
McMaster doesn't carry from them that I use for restoration.

Bolt Depot

Another source for wood and machine screws that I've ordered from.

Want to share the seller and/or the assortment you found most useful for our needs? ... Cuz if you search brass screws you get a TON of selections.

The smallest I've ever found in a non-specialized store were #4s. I found some #2s in a specialized hardware store locally, the box was +50 years old and missing 4 screws. I haven't felt the need to buy anything smaller, given the shipping costs from a place like McMaster Carr to Canada, but the next time I buy something I will throw some #0s in with the order.

I search on "brass wood screw #2" and it narrows down the results a lot. Then when I find a vendor of interest I look at their other offerings and generally find a selection of other sizes. But prefer Microfasteners, McMaster Carr , or the like.
