WebbAs seen in the chart – these classes of fit do overlap even though they are progressive in accuracy. To further break down the accuracy of these threads we have “H: limits in increments of 0.0005”. Every size/pitch tap has a specific or given basic pitch diameter that is the basis for the “H” limits and the class of fir for that size. tiffany davisonWebbThey were one of the first international standards agreed upon when the International Organization for Standardization (ISO) was set up in 1947.
