Richard,
look to your local hardware store. Here in the midwest , we have Ace, Best, True value , and several other hardware chains that can help you. If no luck there, look up "Industrial Hardware" in your yellow pages. You way have to buy in 100 per box, but they will have what you need. If all else fails, E-mail me with a list and I will be glad to help.
