per inch, while a 1/4-28 (UNF fine) thread has the same nominal major diameter but 28 threads per inch. Metric thread specifications are different because the thread pitch is defined by the distance between each thread in mm instead of threads per inch. For example, an M12x1.75 (coarse) thread has a 1.75mm pitch, while an M12x1.50 (fine) thread
