My 2¢ worth... I have heard these referred to as "Speed Nuts". McMaster-Carr shows the ones I am familiar with in their catalog, calling them U-style clip-on nuts. (I found them by doing a search for "speed nuts".) These are designed to use sheet metal-type screws, which is what I usually see in radio cabinet rails.

The ones that are threaded for machine screws are called cage nuts. http://en.wikipedia.org/wiki/Cage_nut 10-32 would be the best thread size to use, since it's a defacto 19" rack mount standard. I've also seen racks tapped with 12-24, but that screw size isn't as easy to find. Bob NO6B
