Unless you are talking about a press fit location or some kind of high precision alignment issue, almost nothing needs anything tighter than .001" and .005 or .010" is perfectly fine for most things. I work with a lot of weldments so if we’re within .030" we consider that good enough.
+/- .030 good enough for most skin panels on airplanes.
Gear teeth I believe need to be precision ground to less than a thou for best efficiency and life. But that’s not for most things.
