* Easy access to all the data charts that appear on this page. Possible Diameter/Pitch combinations. The Unified Thread Standard (UTS) defines a 60° thread form in Inch dimensions as described in the ASME B1.1 standard. It is the North American equivalent of the ISO metric thread system.
The document is a chart listing common UNC and UNF thread sizes used for taps. It provides specifications for each size including threads per inch, major diameters, effective diameters, and drill sizes needed to tap each size of hole.
These are general tap recommendations to produce the Class of Thread indicated in average materials when used with reasonable care. However, if the tap specified does not give a satisfactory gauge fit in the work, please consult the factory.
