Each thread size has a defined number of threads per inch (TPI). The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI and OD of the thread are required for positive identification of thread size because several sizes have the same TPI.

Once you have the thread size, you then need to determine the number of threads per inch to verify that it is a BSP fitting. You can do this by counting the number of thread crests over a 1/4” length, then multiply it by 4 to get the number of threads/inch. For example, if over a 1/4” distance you find 3.5 thread crests:

Jan 13, 2005 · Standard screw threads consist of the Unified inch series and the Metric series. Unified inch series, dominant in the US, are based on the major (outermost) diameter and the number of threads per inch. The three standard series are designated UNC (coarse), UNF (fine), and UNEF (extra fine). Typical specifications are. 1/4-20 UNC or 1/2-20 UNF,
