NOMINAL DIAMETER (NOMINAL BOLT … The size of a metric screw or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated mm). For nuts, size will appear as diameter and pitch. There is an exception though—if pitch isn't specified, the fastener is coarse threaded. Consider this size…. M8-1.0 x 20.

LENGTH OF THREAD . M3 and larger thread is tapped thru 25.4 MM in length. Stainless Steel Nylon Parts: M2.5 thread is tapped thru 9.6 MM in length M3 thread is tapped thru 12.7 MM in length. M3.5 and larger threads are tapped thru 25.4 MM in lengths. For lengths longer than specified above, see Depth of Thread Chart . 499 rows METRIC THREAD -- EXTENDED THREAD SIZE RANGE (ISO) Thread Height Male … Dec 17, 1998 Designation. A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the ideal maximum thread diameter for external thread or the ideal minimum diameter for internal one) and the pitch P, both expressed in millimetres and separated by the multiplication sign, (e.g., M81.25).
