Unless you have some obsecure type of hubs (French, certain Campag, etc) then you will just require a standard track lockring. If you just ask for a track locking you will be fine.
You'll probably need an ISO/English threaded lockring. This is what every bike shop gives you by default if you do not specify the threading. It's 1.29" x 24 TPI.
If you have high quality hubs like Campagnolo, Phil Wood or Miche, they use Italian thread. 1.32" x 24 TPI. I have a sneking suspicion that my Suntour Superbe Pro hubs also have an Italian threaded lockring. After all, they do use Italian threaded sprockets... I would not call any of these brands obscure though. French track hubs are closer to being classified as obscure, but I have to say that every French track hub I have seen (Normandy, Maillard) actually used ISO threaded lockrings, not French ones. Maybe I'm not quite old enough.
My Lollipops disk wheel uses ISO sprockets, but the lockring is a mystery. No-one has yet been able to identify the thread size. It's a good half a cm smaller in diameter than any other lcokring known, so it remains lockring-less. I will allow that one to be classified in the obscure category.
