Does anyone know what size the fixings are that typically come with 3" V-band exhaust clamps? I know they take a 1/2" socket, but nothing beyond that...

They are all different.

You'll need to get a thread gauge and measure it. Hopefully it's metric but they are all over the place.

Might be easier just to get new clamps.

Cheers guys,

I've bought a new clamp but it was sent with a Nyloc nut! I wanted to replace it with something more sensible.

I'd wager it 1/4 x 20, that's what I've found in 1/2" hex, haven't stumbled across metric in clamps at all I must say. I'd try someplace that caters to trucks to buy the silver plated tight nuts. Someone did try to supply a nylock clamp to me sometime ago, funnily enough, they found a proper one when I told them to FO with that!

Take it down to any good hardware store and ask for help!
So simple!

Just realized, I've got some 1/4" nylon UNC bolts on the brain atm and led you up the garden path, if it's 1/4", it will of course be UNF and 28 tpi!!

If all else fails, - and they won't sell just a nut, the usual motorsport suppliers over there should have silver k-nuts or jetnuts that are used on carbon/carbon brakes, they'll be a quid or two each, only 3/8 hex, so will probably benefit from a stainless washer underneath.....must use antiseize on first installation, otherwise tears will ensue, as they have deformed threads in the nut for locking.
