Well the 2 1/8th standard, I have that but should I really risk using a standard on a metric nut of that size and torque?

To my knowledge, they are basically identical. I'll find a converter to make sure.
Edit: 2 1/8 inch is less than 1/1000th of an inch too big, so it will work fine, especially on a nut that big.

54mm is official.
2-1/8" is close enough.

1/2" Impact with with either of those sizes takes it right off. The bolt on the front of the e-shaft is another story sometimes.
