To be accurate, 3/4 is actually 19.05mm, and while a 3/4" socket would work on a 19mm bolt, a 19mm socket might not work on a 3/4 nut, and a 13/16" is actually 20.6375mm, so a 21mm socket would work on a 13/16 nut, but a 13/16" socket might not fit over a 21mm nut. I know it's splitting hairs, but again, the right tool for the right job.
I'll just buy both metric and sae and find one that fits.![]()
