The Ulitmate Metric Screw Thread Resource: Basic Dimensions, Classes, Tolerances, Formulas, Charts, and Explanations
ISO 724 specifies basic dimensions of metric threads in accordance with ISO 261. Dimensions refer to the basic profile in accordance with ISO 68. The pitch varies from coarse to extra fine with up to 5 different pitches for some dimensions. The thread angle is 60 o and the thread depth is 0.614 x pitch.
The Metric Thread Chart PDF is a comprehensive guide that will make finding the right metric thread size easier than ever. It lists the major diameter, thread pitch, minor diameter, and pitch diameter for all metric thread sizes.
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 ...
