WebSep 15, 2013 · A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by the multiplication sign, × (e.g. M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ISO 262, it can be omitted (e.g. M8). WebEach thread size has a defined number of threads per inch (TPI). The 3/4" NPT pipe thread has 14 threads per inch.
