Help me identify screw threading

Does anyone know, or can help me identify the screw threading dimensions/pitch hidden below the middle section/height adjustment knob on a standard microphone stand?

It's and old stand, and the height adjustment knob became brittle and broke. SO, id like to pull the inner rod out, and "cap it" with something from the hardware store.

Odd question I know, but as usual, I don't have a lot of disposable income and would still like to use the remaining part of the stand to clamp lights to.

See images for clarification.

Thank you!

Is there a standard for that? I'd take the stand to the hardware store and let them help you. I think you're going to be very lucky to find a cap for that since it is a big diameter and fine pitch.


If all your looking for is something to cover the threads, maybe a PVC plumbing cap will fit over it. It won't thread correctly, but it is soft plastic and would conform to the threads. You could get lucky with maybe a 1/2" or 3/4" cap (assuming your in the States). Paint it black. A bit ugly, but it might work.

First if you just want to know the thread thee are tools for that. You can probably get a good guess by measuring the diameter and counting the threads per inch. Depending on where it came from it will either be US standard or metric. In either case there are only going to be one thread series that is close, and that is what it is.

You can buy taps and dies for that if you want to thread something to fit. It will probably be a "National fine" thread if its a US thread series. For a given diameter there is usually a national course and a national fine thread (1/4-20 VS 1/4-28) metric probably has similar but?

PVC is useless for most things. It won't have a NF series because the thread is to fine for the weak plastic. It will come in "pipe thread" sizes and that is not close to what you have. Pipe thread is tapered so the farther you threaded it the tighter it gets. It is also very course threads.
 
Honestly, if you know the manufacturer it’s worth it to ask how much a replacement part might be. Very possible you could waste a lot of time & money on solutions that don’t work. It can’t hurt to ask.
 
This is a bit silly. It's a bog standard design based on the excellent K&M stands from Germany, copied by the Chinese and very popular in Europe. The copies are also excellent. Decent boom stands in this design go for less than twenty UK Pounds!

You can even buy genuine parts for K& M from people like Studiospares in the UK. These however, can be quite expensive. If US plumbing stores are cheaper than ours, mending an old one could be OK, but mic stands need to be quick and simple and one handed to move. Bodges that might cut fingers, have sharp edges and are just awkward make no sense.
