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 has a 1.50mm pitch. Both DIN and ISO standards for metric threads ignore the pitch callout on coarse ...

A thread chart is a reference for identifying the types of threads and the suitable replacements for a given product. It is helpful in determining the right thread size when repairing or replacing parts in machinery, tools, and other items with threaded connections.
