I've had good luck and pricing from {http://www.boltdepot.com/}. Shipping is cheaper if it's a business address since they use UPS for everything I've bought.

lots of fastenals around i get stainless 3mm with the lock nuts from them .they are reasonable,unlike Brafasco you can buy 1 or 2 ,with Fastenal you need to buy a minimum quantity to get them orderedwhich is good because you will need the extra later
