I'm looking for a threading die for garden hose fittings.
I think this might be 5/8"x14 NPT. All the standard tap
and die sets skip over this size. Doesn't have to be
particularly good quality, carbon steel would be okay,
just want to chase threads on an old faucet that has
developed mineral deposits to the point that I can't
get a hose to screw on anymore. The faucet is otherwise
in good working order, and I hate to have to replace it
just because it needs cleaned up a bit. The folks who
make these parts have to have taps and dies, right?
So what are they using and where do they get it?

A male garden hose fitting on my bench is 1.050 over the threads,
pitch is 11.5 TPI. That's probably nominally 1-1/16 - 11.5. I
think I have seen dies like this in a catalog, but I lathe-cut them.

You should be able to clean up your faucet with a mild acid (vinegar
or dilute muriatic) or a household lime remover. A brass wire brush
may help.
