Hi
Ive a tap/faucet to fit, but but no 'fittings'!
Does anyone know where I may be able to get some (horseshoe washer, 7mm bolt etc), as I've tried our local diy stores & plumbers merchants, with no luck?

Are you looking for things such as this?: Horseshoe Washers on Hubbard, M. D., Spring Co., Inc. (http://hubbard.thomasnet.com/viewitems/washers/horseshoe-washers)

For your 7mm what kind of head and length are you looking for?
SmallParts.com: The Hardware Store for Researchers and Developers (http://www.smallparts.com) sells small quantities.

I needed a 6-32 or 8-32 carriage bolt and I had to buy a 100 somewhere.
