Did you also notice that most of the threads went with a certain
diameter? There are several different standards and what you ask
for is nothing standard at all. You won't find a 1/2-40 bolt anywhere,
most likely.

I did of course know and notice that... But that's why I'm asking here and
searching. Because there is always something new for me to learn and since
I need an answer to this and wanted an easy source, I figured I'd look.

BTW - MSC has the 1/2-40, 48 and even 56 taps for sale as "specials" so
someone must make a "special" bolt too. I doubt many of us will ever see
one, but someone must be using them somewhere...

Sure you wouldn't settle for a thread pitch gauge? They're $6 at HFT.
(When you can find them.)

I actually need the rod for a project...

Give www.mscdirect.com and www.use-enco.com a looksee.
Alternatively, head down to the local machine shop and ask any
guy with a toolshop lathe to cut one or more for you. Most metal
lathes can do most of those threads on any diameter rod without any
problem.

I'll try use-enco.com and see what they come up with... However, I agree
that the machine shop answer is probably the best solution long term.
