UK Supplier of screw type scale pins

Hi there if this is in the wrong place then please move it!!
I've found a UK supplier for hexagonal screws, nuts and washers if anyone needs some
WWW.gwr-fasteners.co.uk.
I've used 10BA and these seem to fit ok. The only thing I can't find over here is the thin pivot washers

I don't have the shopping list but you can find that easily with a google search here in the forum, but are they cheaper than microfasteners? They deliver worldwide with something like 7 USD extra.
