WebA thread size is specified based on a nominal (major) diameter and either the number of threads per inch (for unified inch threads) or the pitch (for metric threads). The thread sizes for coarse thread and fine thread can be found in tables located in any standard machine design handbook, as well as in the thread size tables in the Appendix.
