Can I get recommendations of which and how many screw thread

There seems to be a lot of overlap between gauges and I just want to
get what I need.

Thanks.

What sort are you looking for? The kind with folding leaves and teeth
or the ones with threaded holes? I have both sorts as well as the
threading gage for setting up lathe tools. The one I have that I use
the most is Starrett, it's triangular and goes up to like 84 tpi. I
have a metric one I inherited, the screw plate sort I bought from
Brownells back when they were much more reasonable in price. Also has
the ******* threads they use for scope mounts on it, one reason I have
it.

Just looked up the Starrett, it's #472 in the catalog, no idea of
current price. Listed under "Screw Pitch" gauge, if you want to
actually check if your cut thread will fit in a tapped hole, get the
screw plates.
