Does anybody have any idea what the 3/8 unf wheel nut minimum internal diameter might be?
I've a couple of new ones that measure close either side of 8.3mm id, and the one that the garage overdid measures 9.3mm. So that
gives me the limits.
But where less than 9.3 is good enough for road use, and where wants replacing?
I've also got 4 well used spares that look good in the thread and measure up to about 8.5mm.
I plan on looking at what the ones that still take 48 lb.ft (65 N.m) of torque on the car are.
But is that they take torque the only measure that matters or, if I find some are a bit big, like 9mm or more, should I worry, and how much?
