Where can I get a spare screw for my RSST?

[Steez]

Well I was cleaning out my RSST over the sink and there went my little screw that locks in the wire down the drain lol. I haven't been able to find any vendors that carry spare parts, maybe I can run down to Home Depot and buy one? But i'm not too sure on the sizes either..

did the same thing... home depot didn't have anything close, so I went to radio shack and found their smallest size screw packs which worked.
