I'm in need of some #6 x 1/4 and #6 x 3/8 sheet metal screws, slotted, pan head, grey zinc finish, which are a US spec. These equate to a 3.5mm diameter in metric terms, but can't seem to find a vendor selling these in "home user" quantities, don't want to buy more than 50 of each size.
Any good leads?
Many thanks
Steve
