Black Oxide, Brass, or Plain old steel Nuts needed for a project.

[Pmedic828]

I am working on a project that uses #3-56 #3-48 and #2-48 and #2-56 cap screws and have ordered and received a few from on line - I cannot find any matching nuts and wonder if anyone would be willing to send me 3 or 4 of each size in an envelope. They are light and shouldn't cost a bunch. If you have a few and be willing to donate, please I M me and I can forward my address. Many thanks to a novice that has learned many new and interesting things from this site -

I might have a pillbottle with used 'uns, but it'd take a bit of work to figure out what size the nuts
are; I just scarfed 'em from old widgets.
Regular old suppliers don't charge much, though:
<https://www.mcmaster.com/#92671a003> #2-56 brass, for instance, is under $3 per hundred.
Shipping extra, of course.
#2-56 and #2-64 are standard sizes, not sure about #2-48.

Yeah, #2-48 is special. Standard is 2-56 and 2-64. Not much cross section left with 48 TPI..
