Where can I purchase alloy steel hex head 8-32 bolts?
They need to be alloy steel (not stainless, not titanium, plastic
etc.).  The length is not too crucial.  They are also preferably not
ridiculously expensive either... what I mean is, a good answer does
not involve getting them custom machined/treated etc. for $50 a bolt. 
8-32 is a standard bolt/screw size (Number 8 is the size, 32 is the
number of threads per inch), but I just can't find any with a hex
head, which seems odd to me, since hex heads are pretty standard.  The
preferred answer will contain contact information for a supplier that
can ship to Canada.

Found a couple of possible sources:

toll free number included

to order

Good luck.

I am investigating these options.  I will respond again when I get in
touch with them.

The first link is for "Hex SOCKET Head" which means that it has an
internal, hex shaped hole that you insert an allen key into... this
isn't what I need... it needs to be a regular hex head... one you
could put a wrench onto.

I called the second company, and after being passed around to
different branches in the US and Canada, determined that they do not
in fact make the correct product, despite being able to select it in
their quote form.  The form is very general though, it just has every
size of bolt and every length etc.  They do not make all the possible
combinations.

I guess this is an oddball item... but no one seems to know why...

Hex Head Bolts 8-32 are normally found with an attached washer only.
They are a special item, that has to be manufactured per drawing &
specs, if you need it without washer attached.  We can supply them to
Canada.

Sounds good.  I've emailed Rodrigo, and hopefully he will confirm
everything with a quote.  I assume your last comment is a response
from him?  Getting them with a washer is a bit weird, but probably
ok... as I said in my question, I don't want to get them custom made
(likely expensive) which is what he seems to be suggesting for without
a washer.

I'll reply here again when I get in touch with Rodrigo.  Sorry if I
seem skeptical, but lots of companies seem to initially think they
have the correct product, but it ends up that they don't...

Hi scottwebster-ga I can understand you're skepticall, it's a
difficult item.  I jost hope you get what you want.  In fact what I
wrote before is an answer from Rodrigo.  He does have them in stock
with a washer, unless he is confused whish is not likely.  Also labor
is pretty cheap in Mexico, consider the custom made part anyway.  Good
luck!
