Summary In 2003 the ASME B1 Committee finalized changes to ANSI B1 1 This page only talks about pitch diameter changes Many of the tabulated screw thread pitch diameter sizes remained the same The tabulated screw thread pitch diameters which changed only moved 0 0001 to 0 0002 of an inch This small amount of change is considered insignificant to fit and function of
