Thread calculator All calculated results are based on Basic outside diameter number of threads per inch series designation and class tolerances The algorithms used for this calculator are based on the my best interpretation of the ANSI ASME B1 1 1989 specification UNF Unified National Fine Thread Female and Male UNC UNF threads are both parallel The UNC UNF flank angle is 60 Unified threads comes in three different classes for applications where a liberal tolerance is required to permit easy assembly even with slightly nicked threads
The UNF 1 4 thread has an outer diameter of 6 35 mm the M 6 thread has precisely 6 mm work tolerances are possible We recommend to use only the UNF 1 4 28 G thread to avoid confusion and double inventory General Note All dimensions expressed in inches Supplements Thread calculators and charts ASME UN screw thread calculator Reference ASME B1 1 2003 Unified Inch Screw Threads UN and UNR Thread Form Oberg E Jones F D Horton H L Ryffel H H 2016 Machinery s Handbook 30th edition Industrial Press Inc
