2023年7月25日 · In this blog post, an experienced mechanical engineer demystifies thread pitch and explains how to decipher the code. With clear examples and helpful charts, you’ll learn the difference between metric and imperial thread standards and …

The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its major diameter and its pitch.

Our user-friendly metric thread chart offers comprehensive specification data for various metric screw sizes. Our thread size chart covers M1.6 up to M68.

Thread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts.

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 ...

The tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. The decimal equivalents of the diameters are shown in both English and Metric units.

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 …
