Finally, 20 is the length of the bolt in mm, measured from the tip of the thread to the bottom of the head (with the exception of oval headed bolts). Do not substitute without proper engineering evaluation. of Threads/Inch BA BSW BSF BSP Major Dia. However, if a fine pitch thread is used, the M and associated diameter value will be followed by the pitch. Thread Pitch. To measure thread pitch, use a caliper and measure from the peak of one thread to the next. The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1.
