coupling nuts

[Factory51]

Hi, Does anyone know where I can buy 1/4 x 20 coupling nuts from in the UK?

I've searched ebay, screwfix, many other hardware places, but I can't seem to get hold of them

Here is a picture of them if you don't know what they look like

any one knows where I can get them, please could you email me on factory51(REMOVETHIS)@googlemail.com

Cheers

Simon

Commonly used in electrical assemblies, and available from the likes of CPC/Farnell/RS, etc.

You read replies here.

==================== If you only want a few you could buy worktop clamps and use the nuts which are for some reason the nuts you're looking for.

See here:

Mart also sell them.

thread type and length. If you mean 1/4 inch AF (approx) by 20mm long they'd be M4 x 20, and the RS number is 222-496. They're chrome plated brass and cost 0.17 each plus VAT - but come in packs of 50 minimum.

[Factory51]

Hi, are the worktop clamps the same size of thread?

Thanks

[Factory51]

Ok Cheers, they are to fit a camera tripod screw thread for a project that I'm doing at uni, I've been told that 1/4 is the correct thread?

Yes - correctly 1/4" BS Whitworth, but 1/4" UNC will just about fit.

[Dave Plowman (News)]

Ah - right. Yes, that's 1/4 BSW and much bigger than the spacers I've mentioned. It's also the tread size used for microphone stands. Have a look at Canford Audio

give your local disco/music shop a try.

[Factory51]

Does RS not have the ones I want then?

If so which are the rs codes for the 1/4 BSW

thanks

==================== Those I have are M6 thread and the nut is about 17mm long.

I've had a good look on that Canford site, and they cost =A313 each! for what want.

I can't find the right ones on the rs site, can anyone point me to them please

Thanks

I was wondering if they were called something else and found this site which I found interesting considering the depth of my engineering ignorance:

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember " [e-mail]" saying something like:

Make your own. Cut a piece of hex bar, drill and tap it the right thread. If you've got a few to do, it's cost effective compared to that price and is more in keeping with the spirit of this ng.

[Factory51]

Too much trouble that one mate, i'd rather just buy them ready done, i'd order the ones from RS, but I dont know which ones they are.

[Dave Plowman (News)]

As I said before, the largest they do in this style has an M4 thread, and the outside size of the spacer (across flats) is approx 1/4" so it couldn't even be modified by re-tapping to suit.

This sort of thing for camera or microphone use tends to be limited production (as you've found) so expensive. But you might find a mass produced cheaper item in a disco equipment etc store.

RS 276-522 is M6, described as "studding connectors". I think I found them in the section that deals with suspending things from factory roof girders.

[Dave Plowman (News)]

Ah - right. ;-) M6x1 does sort of 'go in' a few threads of a 1/4 Whit but not really to be recommended, given the cost of some cameras.
