I have tried to manually change the dimensions but that does not work.Tapping hole tolerances. Tap tolerance vs. tolerance on internal thread (nut) Normal tap tolerance is ISO 2 (6H), which generates an average quality fit between screw and nut. Lower tolerance (ISO 1) generates a fine fit without a gap on the flanks between screw and nut. Higher tolerance (ISO 3) generates a rough fit with a large gap.Nov 12, 2021 ...
