Major Diameter (mm) Explained. The major diameter in our bolt size chart, typically measured in millimetres (mm), refers to the largest diameter of a threaded cylinder, also known as the crest of the thread. This is a critical parameter as it essentially dictates all metric bolt sizes.
The metric thread chart PDF provided on this page is a free download that you can print out and use as a handy reference guide. It contains all the major metric thread sizes and their specifications, including their thread pitch, major diameter, minor diameter, and pitch diameter.
