Bearing in mind Shazaam's caveat about electrolytic corrosion

, who do youse guys use as a UK stockist for stainless screws etc?
I've tried Google, and searched on here, but it's hard to see the wood for the trees. Way back when I used to use a guy called David Middleton, up in Yorkshire somewhere. But I don't think he has a website, think it's postal via a catalogue only.
TIA.
