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 Coarse Thread UNC Fine Thread UNF Pitch Size TPI Size TPI Size TPI Size TPI Size Coarse Fine 1 64 1 8 0 80 7 8 14 M4 0 70 0 50 2 56 1 1 8 7 1 72 1 121 M5 0 80 0 50 3 48 1 1 4 7 2 64 1 1 8 12 M6 1 00 0 75 4 40 1 3 8 6 3 56 1 1 4 12 M8 1 25 0 75 1 00 5 40 1 1 2 6 4 48 1 3 8 12 M10 1 50 0 75 1 00 1 25THREAD DATA CHART Metric Thread Fine Pitch Nominal Size ISO MF Thread Form Type Major Diameter mm d D Pitch mm p Root Radius mm r Pitch Diameter mm d2 D2 Minor Diameter Male Thd d3 Minor Diameter Thd D1 Thread Height Male Thd h3 Thread Height Thd H1 Tap Drill Diameter mm 1 0x0 2 M 1 00 0 20 0 029 0 87016 rows nbsp 0183 32 Metric Thread Pitch Table Print this page Bolt Diameter mm Thread Pitch mm Standard Fine Extra or Super FineMetric thread calculator to calculate external and internal metric thread dimensions including major diameter minor diameter pitch diameter and thread tolerance according to ISO 724 and ISO 965 standards There are two calculation options available general engineering use
