Re: Mic stand threading - two types or three???

I'm having a problem connecting mic stand parts, and it has me puzzled.
I was under the impression that there were two types of mic stand
threads - 5/8" 27 pitch US, and 3/8" European. But I'm running into
some parts that appear to be 5/8" male that will not attach to various
5/8" female connections, such as mic clips or a Shure A27M stereo bar.
The problem parts are various 3/8 female to 5/8 male adapters.

OK, so I got some junky parts. Except for two things: I also have a
couple of jam nuts that fit the problem 5/8 parts perfectly, and the
kicker - I have one adapter that's 5/8 female to 5/8 male. The female
side mates perfectly with the problem adapters, and the male side fits
perfectly into the A27M. And (woe is me) I don't know where I got this
magical part.

So, can you point me to a source for 3/8 female -> 5/8 male adapters
that implement the 5/8 27 thread or a source for these magical 5/8
female -> 5/8 male adapters that fix the problem thread?

Thanks very much,
Fran
It sounds like you have some poorly cut male threads. You could use a
5/8"-27 die and die chuck to clean them up and make them fit. The jam nuts
likely are over tapped and a bit loose on a good 5/8"-27 stud.

BTW ~ There actually is a third (albeit obsolete) standard: 1/2" NPT
(pipe)!
