Do you have an Italian hub Tommo ie is it by Miche, Campagnolo ? They use a thread 35mmx25tpi with a thread angle of 55 deg. If it's a Shimano, Formula, Suzue, Phil, etc. then it uses a BSA thread - 1.37" x 24tpi with a thread angle of 60 deg. While the differences are tiny and you can get a Miche / Campy cog on a BSA thread the contact area is reduced and you risk a stripped hub. Hope that helps
