There are 3 standards for threads...As you can see they are very similar. I know(because I have done it) that you can go from Italian(Miche) to English(DuraAce) with no trouble. Once you decide which standard you want to follow, you should probably stay with it..since there will be some deformation of the threads if you jump back and forth.
English 1.37" x 24tpi (current standard),
French 34.7mm x 1mm,
Italian 35mm x 24tpi
For lockrings there are the 2 major standards
ISO/English standard size 1.29" x 24 TPI fits most U.S., English, and Asian fixed gear hubs.
Campy/Itailian are used on Phil Wood hubs, and most Italian-made(Miche) or French-made hubs.
