The thread series is generally relative to the outside diameter of the screw . 20 threads per inch on a 1/4 diameter screw is considered coarse: 1/4-20 UNC. On a 3/4 diameter screw , 20 threads per inch is considered extra-fine: 3/4-20 UNEF. Screw Thread Calculators given in the following chart are categorized as Metric threads , Unified threads , Acme threads , Buttress threads and Pipe threads . Screw thread calculators can be used for the calculations of different screw parameters such as tap drill sizes, thread size calculations with tolerances, bolt torque calculation , etc. Calculators ; Screw Threads ; METRIC THREAD SIZE AND TOLERANCE CALCULATOR (ISO M THREAD ) Metric thread size and tolerance calculator was developed to calculate major, minor and pitch diameters of the external (bolt) and internal (nut) metric threads according to ISO 793 standard.
