I have some Alps potentiometers and rotary switches without nuts, and
I'm trying to get some to fit. I think it's something like the
following:

i.e. M8 with what looks like .75 pitch

Is this common stock or do I need a specialist, if so who?

I'd be tempted to take a trip to the nearest Maplins to see what
they'd recommend :-}

If you can't find any you could get a lump of M8 studding and locknut a
couple of nuts on the end and grind them, or rather the end one down to
the right thickness....

Any good?

This is 1.25 pitch. I think my problem is that this is the usual pitch
for M8, but the Alps is 0.75. I guess that being a thin nut they
wanted more purchase.

So basically still searching (and waiting for a reply from Alps)

Check out
Modern Screws of Bexley Kent.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Eusebius
saying something like:

I'd be surprised if RS or CPC/Farnell don't have securing nuts for pots
and switches. NR Bardwell is another that springs to mind.
Used to be ten a penny at any component stockist.

Is it ISOmetric extra-fine? I dimly recall having something like M10 at 1mm
pitch or thereabouts; fortunately we had sets of taps and dies for EF
threads.

It's not rocket science, you know.

If you want to roll your own http://www.tracytools.com/ may do the
taps.
