The common Vthread standards (ISO 261 and Unified Thread Standard) include a coarse pitch and a fine pitch for each major diameter. For example, 1 ⁄ 213 belongs to the UNC series (Unified National Coarse) and 1 ⁄ 220 belongs to the UNF series (Unified National Fine). Similarly, M10 (10 mm nominal outer diameter) as per ISO 261 has a ...
Metric threads are designated by the letter M followed by the nominal major diameter of the thread and the pitch in millimetres. For example M10 x indicates that the major diameter of the thread is 10mm and the pitch is The absence of a pitch value indicates that a coarse thread is specified.

UNC threads are the most common form of imperial thread in Europe. This type of thread is commonly found in legacy projects, and is still widely used throughout the US. Unified Fine Pitch Thread (UNF) UNF threads are the fine pitch variant of UNC threads, their finer thread pitch can be visually distinguished from UNC threads.
Threads are found on screws, nuts, and bolts. THREADS PER INCH The decimal equivalent of the number of threads in an inch. COARSE THREADS FINE THREADS Coarse threads are those with larger pitch (fewer threads per axial distance), and fine threads are those with smaller pitch (more threads per axial distance).
