Where to buy M7 stainless bolts?

I need to replace two annoyingly sized M7x20mm allen-key headed bolts in an older stem.

I don’t suppose anyone either has a couple of spare stainless ones (the old ones are horribly rusted) or knows where to get them, that doesn’t charge a fortune for postage like SJS?

Try http://www.kkckartshop.co.uk or http://www.kartnuts.co.uk

ebay is pretty good for small quantities of bolts and cheap postage

As above ebay or look for a local fixings and fasteners place.

I’ve tried all the local wholesalers and bike shops, nobody stocks M7. Ebay only seems to have Ti bolts shipped from china, so I’ve given up and paid SJS – postage is more than the bolts, but I do get four in a pack.

Next question – where to get 3/8th inch purple alloy axle nuts to pimp a kids bike…
