The following are metric external thread size table chart for sizes M20 to M55 per. ANSI/ASME B1.13M-1995. These thread sizes and classes represent bolts and screws, as well, as other standard external threads. Do not use these values for standard metric internal thread designs. All units in mm. Related:

Bellow are ISO/DIN accepted thread pitch charts for commonly found metric fasteners. Here is Lightning Bolt’s Metric Bolt Thread Pitch Chart. In the Imperial “inch” system, threads are commonly referred to by measuring an inch, and counting how many threads are …

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 ...

Generally minor diameter acceptance is based upon maximum material condition gaging.

A reference chart to view the thread pitch for metric coarse, metric fine and extra fine and imperial fasteners UNC (unified national coarse) and UNF (unified national fine) and includes hard to find fasteners like BSW (British standard whitworth), BSF …

The main feature here is the thread pitch. The best way to determine the thread pitch is to use a caliper gauge to measure the distance between two threads. The following table lists all thread pitches for metric standard threads from M1 to M60.
