It's 0.0015, that's 1.5 to 2.5 thousandths, or 15-25 "tenths" as they're called.
That's not a particularly tiny gap in the machinist world, it's large so that you can pump viscous oil in it and deal with a wide variety of temperature changes.
25 thousandths would be sloppy, a nominal clearance hole for a 1/4x20 bolt is about that much.
- arlattimore 3mo agoGood catch, sorry should have corrected that. While not small for a machinist, I think by the average persons definition that is a pretty small gap for the oil to occupy ;-)
- cagey 3mo ago> 25 thousandths would be sloppy, a nominal clearance hole for a 1/4x20 bolt is about that much. Isn't that 0.250 which would be 250 thousandths?
- teraflop 3mo agoNo, they're talking about the clearance, which is the difference between the diameter of the bolt itself (1/4") and the diameter of a hole in which the bolt loosely fits (a couple hundredths of an inch bigger than that).
