What is this thread adapter?

[J.S.Vega III]

Hi guys, I've got two mic stands that my 5/8" female -3/8" male thread adapters will not fit.

I only have one of the "right" kind of thread adapters (and about 30 wrong ones) and would like to get more but I simply don't know what they're called.

The adapter on the left in the picture is (to my understanding) a regular 5/8 - 3/8. Can you identify the one on the right? It's basically the same, just about 2mm wider inside, and it fits my mic stands perfectly. The external thread of both fit in a 5/8" female mic clip.

Many thanks!

What make/model mic stand is it? Did that adapter come with it?

[J.S.Vega III]

Not sure what make or model the stand is, I remember peeling off the label as it was all in Chinese. The adapter didn't come with it, it's just one I had floating around.

It looks like a 1/2" thread - Neumann often use this.

Some adaptors like this have 1/2" one side, 3/8" the other and the horrible American 5/8" threadon the outside.

What happens if you flip it around? Sometimes the thread size you are looking for is on the other end.

[J.S.Vega III]

Yes! I believe it is 1/2" - however a search on ebay for that doesn't reveal any results for me. None of my 3/8" adapters will invert.

Does anyone know where I might be able to get hold of a few 1/2 inchers?

[J.S.Vega III]

OK from googling I found that the 1/2" thread is possibly a Japanese standard, looking at Canford's site it seems they sell them.

Thanks a lot fellows!

That's interesting. When I was in Japan all the mic stands were 3/8". I don't know what brand they were, though.

the other and the horrible American 5/8" threadon the outside.

Don't you know bigger is always better?

[bishopthomas]

Do you want to supersize your mic stand thread?

[pkautzsch]

K&M make one stand that needs a 1/2" adaptor, and they sell the adaptor as a spare part too. Don't know the model number, but you can search their website.

But the threads are so fine - get dirty easily and often bind.

Well, at least they're not that communist ***metric*** stuff! <shudder>

The 5/8 threads work fine for me. I have never had a problem with dirt being a problem when used inside. I like that a fair share of the threads actually go into the microphone clip and feel secure. The only draw back is since the threads are fine they are more prone to damage. I always use the brass adaptors when adapting from 3/8 to 5/8 they seem to last the longest.

I understand that in the 1940s, the only tubing available that didn't weigh half a pound per foot was domestic electric lamp tubing, which was thin-walled brass & used American Standard Fine threads (27 threads per inch); all the tubing/piping which used American National Standard Thread or Coarse had much heavier wall thickness - imagine the tipping moment of mic stands made from 1/2" steel pipe. It is still very difficult to find a 5/8"/27TPI tap and die so as to cut custom ferrules and adaptors. 5/8" was also conveniently the same size as the "Baby" lighting stud, requiring only a simple adaptor for use on Hollywood sets. A 5/8-27TPI to Baby female 5/8" stud receiver would be a useful collar to have in the road kit, Mr Atlas/Manfrotto.
I've made a couple out of brass but they're a bit kludgy.

Gabriel Mouton, the vicar of St. Paul's Church in Lyons, France, is the founding father of the metric system. It dates to 1670 which is a little before Marx.
The actual fully conceived metric system was instituted in 1790 in France.

No they are good old 3/8" British Whitworth - technically the best thread there is.
