Gayle, I think that you will be better off to find a fastener source in your area. The reason for this is that anyplace that is basically in the mail order business is going to want to sell you 100 pieces in a box of left hand M8-1.25 x 25 or 30mm for about $17-18 plus freight. If you track down a local source, they will sell you a couple for a dollar. Go to a computer "Yellow Pages" for your area and find the closest industrial fastener distributor, then call to see if they have or can get them. This is not something for a local hardware or home center but shouldn't be too strange for an industrial supply source.
