UNC THREAD CHART. UNC thread chart including major diameter, pitch diameter and minor diameter dimensions of UNC screw threads according to ASME B1.1 standard.

Thread series cover designations of diameter/pitch combinations that are measured by the number of threads per inch (TPI) applied to a single diameter. Coarse Thread Series (UNC/UNRC) is the most common designation for general application bolts and nuts. Coarse thread is beneficial, because they are less likely to cross thread, more tolerant in ...

THREAD PITCH CHART (UNC / UNF / UNEF / UN) Thread pitch chart for UNC, UNF, UNEF and UN up to 2 inch according to ASME B1.1.

Unified inch screw thread (UN and UNR) design profile for classes 1A, 2A, 1B, and 2B according to ASME B1.1-2003 - ASME B1.1-2003 standard covers for UN and UNR thread forms with sizes from 0.0600 inch to 6 inch. - The difference between UN and UNR thread forms is the form of root section. For UN thread form , the root of the thread is flat.

To use the standard pitch diameter chart for thread plug gages, match the thread size you are working with to the chart's listed sizes. This will provide you with the go/no-go measurements necessary for ensuring your threads meet the specified tolerances for …
