It is not going to be a Press Fit with a +/- .010" tolerance

Note how it is used P.S. = Press Fit not just straight PS = Parallel thread for Jis standard, so it has more than one meaning depending on how it is written and what it is referring too

I wonder if the Machinery Hand Book has how it should be used
