Does anyone know where to purchase threaded rod at 5/8" 27 TPI? I need to cut up some pieces at different lengths to mount mic clips on weird surfaces. Sort of an experimental art recording project I'm doing. I have searched high and low and come up empty. Of course, someone in the world makes the damn things. I just can't find them! Much obliged.

not sure if this helps but..

here is a flexible one for $6.95 which has a male one end female the other. flexibles are available in many lengths and arent terrible priced compared with others i've seen.

look at page 2 of this pdf. it looks to have some sort of extension rod which is somewhat like what you wanted. cant vouch for a price though.

why is 5/8 27tpi hard to find? because it is non standard and is only used in that industry because manufacturers profit from it.

if you can find a 5/8 27tpi tap you would be better off buying 5/8 pipe and tapping it yourself. this is what you would call the cheap option if a...

Thanks for the replies. I'm familiar with McMaster, as I've ordered a lot of different parts from them. But they do not have this size stock. Neither does anyone else, apparently.

5/8-27 is the threading used for mic clips. In fact, ALL microphone stands, clips, couplers, extensions etc. are 5/8 27, except the European 3/8 version which is of no use to me or just about anyone else in the states. Odd, since there are millions of parts sold in audio and other stores around the country with that threading.

I've found the die and could do it by hand but it wouldn't be precision enough. Someone machines these things. Just can't find them!

I'm absolutely positive it's not metric. And many many different companies sell mic clips, stands etc. with this threading. It isn't proprietary. I've been in the music industry for twenty plus years. And not a single person I've spoken with seems to have a clue where these are made. Most, if not all, are surely made in China. But when I contacted one of the mic stand companies, for example, they offered nothing. Of course, why would they. They want me to by one of their 3/4" long 5/8" 27 threaded couplers for 6 bucks a pop. They probably cost 50 cents to make, if that. So frustrating.

Thanks for your humble input. If all I needed were a few pieces you'd be right. But a few hundred, that's another story.

if you can find a 5/8 27tpi tap you would be better off buying 5/8 pipe and tapping it yourself. this is what you would call the cheap option if a bit labor intensive. i know you would rather buy pieces pre-made however that is going to cost you much more in the long run. you could even buy two taps and make your own adapters. it might actually even be cheaper to have a machine shop use a lathe and make you some adapters and thread the pipe for you then to buy it online from recording industry manufacturers.

they do make 5/8 27tpi to standard adatpers.

here is a cheap option i found

5/8 27tpi to 3/8 16tpi adapter for only $2.99

you can buy 3/8 16tpi threaded rod at lowes! $5.60 for a 72" piece

ugly perhaps.... but cheap!

Thanks so much for all of your effort and ideas. Much appreciated. I may go the machine shop route and see what I come up with there. Seems reasonable enough. Amazing how such a seemingly simple thing can be so tough to sort out. I mean, the hoarding by the industry is sort of sickening to me. It's not like I can start a mic stand company or something. Oh well. Anyway, thanks again!

well.. if you didnt mind an ugly solution it is hard to beat good old allthread and some $3 adapters.

for a more professional look you could tap the ends of 3/8 rod stock and paint them if using the $3 adapters.

basically you are correct: all of the manufacturers banded together to make a new standard which isnt accepted as a standard by anyone else so therefore its extremely hard to get and expensive. why they do not swap over to another standard i would guess its all for money grubbing.

as far as the machine shop idea... that all depends on how many you want and how much work it is. you can beat $6 but i'm not sure you will beat $3 (but i could be wrong... i dont know your local machine shop prices)

if you went with 3/8 or even any other standard sized rod you could even use standard floor flanges for mounting.

you can even get hinged standoffs like this one... you might need to look around to find a good price though

but you are sure to beat the recording industry prices!

if you build nice stuff for a good price you could start a part time mic stand business actually. some small time garage bands or home studios might appreciate the lower costs.
