What John said is very accurate.
If you want high-quality, tight-tolerance parts, and you want them NOW,
McMC is your best option, but you will pay quite handsomely for the
privilege.
If you're looking for stock, I'd suggest also looking around at the
other online metal dealers (a google search will quickly expose them).
Lead times may be longer, and depending on your needs you may have to
pay cut fees, but the prices will most likely beat McMC by at least a
small margin.
Sadly, new metal is very expensive from the hobbyist point of view (at
least in my opinion), and scrap dealers are few and far between in the
greater RTP area (scrap BUYERS are plentiful, but few sell).
Never buy metal stock from big-box stores unless it's your absolutely
last option (or your needs are for very small amounts). The quality is
low and markups are ridiculous.
Cheers,

+1 McMaster Carr
They have focused on wide variety of parts and getting it to you fast. There
focus has always been Manufacturers. We used to have accounts with them and
could order parts and it would be there the next day with Ground UPS in most
cases if you got the order out by a certain time.
They are my go to for material of all manner. Start there, you can't go wrong.
Two things to know about McMaster Carr.
1. You will not get the best price, that is not their focus. Getting you the
part is their focus, which leads me to #2
2. You will get hit on shipping, In fact you do not even no shipping in
advance. You find out after they ship. They will ship two items from the same
location at different times if they think they can get you one of the parts a
day earlier. And guess who pays the shipping?
These are not negatives, you just need to understand their focus to get that
part to you ASAP.
Also an excellent way to quote assemblies is to price from McMaster Carr and
not include shipping and you will most likely be able to get that part for that
price shipped to your house if you shop around. I'm over simplifying, but it's
a good rough quote if you need something quick.

Dear Triembeders,
Twenty five years ago when I finally pursued a life long goal of getting into amateur
radio some of my "ham" buddies who had more loose change than me uttered two
words any time the subject of obtaining a fastener or raw construction material came up:
McMaster Carr.
Fast forward to earlier this year when I decided to become active with the hobby again (albeit with a single HF band
and limiting myself to "low power", defined in most contest rules as up to 100 watts). Anyway, I'm preparing
to make a series of custom yagi antennas, and if you want these to "stay in the air" for more than a few
months before turning into lumps of corrosion, you stay away from the inexpensive but metalurgically challenged stuff
at Home Depot or Lowes. For instance, even just saying "stainless steel is the last word" only buys you X
years of trouble free service, but if you want to solve for X and ensure it's a large number, you look for a stainless
called "316". But I digress.
For all these years I'd always had one excuse or the other to go to HD or Lowes, order
somebody's pig in a poke off Ebay, etc. But this time I've been systematic. I found 120
SS 316 hose clamps through Amazon, but some very specific size U bolts were pure
unobtainium until I remembered McMaster Carr. You know that scene in "The
Matrix" when Neo needs some weapons and a set of endless rows of shelves of stuff is
conjured instantly? That's what the McM web site is like. If you can imagine it and it is
not a full custom thing, that thing is there. This is only a slight exaggeration (and I
haven't seen evidence of gaps in their inventory yet).
But the real reason I'm writing is about the ordering and fulfillment process. It is,
in my opinion, light years ahead of Bezo's wildest dreams. Amazon is a sparse matrix, and
not just sparse, but mercurial to a sometimes maddening degree (and I'm of course talking
pre-catastrophe). With my two orders so far, not only is it close to "one
click", the fulfillment is rocket sled fast. They don't offer me endless, dynamic
choices and offers of points or money for this or that one: there is no choice unless, I
guess, if I dig in and click around, call them, etc. Instead, similar to with some
electronics distributors, the final shipping (and tax and tarrif) details catch up with
you later. With McM the stuff simply appears, fast.
And finally, there's the old adage that "you get what you pay for". With
McMaster Carr you not only get what you pay for, but you sometimes get the pedigree.
Picture my surprise to get the chemical analysis details and photocopies of inspection
signatures (yes, multiple) and attestations of the origins and processing history of my
item. Say what? I guess these folks serve some very picky customers!
Now I'm sure my first two orders are well within the beginner's luck zone.
But all of this has been by way of saying if anybody on this list asks about
finding an unusual fastener, piece of sheet aluminum, etc, I have just two
words for you. :-)
Pete
