I feel your pain! I remember my favorite science teacher in high school saying that within a few years the US would be on the metric system. Wrong. Still, I now have two totally cluttered tool boxes, one metric and one SAE.I was researching whether to purchase these lug nuts myself. In looking at the specifications; however, I see that they have a 13/16" hex for the nuts. This might not be a big deal to some, but even my domestic vehicles dating back 28 years have no SAE hardware; it baffles me why the aftermarket continues to make hardware for vehicles using SAE dimensions. I personally have moved all of my SAE tools out of my primary toolbox because they were simply clutter. I have some 1984-vintage heavy equipment that I visit that tool box for; not much else.
Not that I have other people work on my vehicles, but if I called AAA for a flat, I would expect them to pull out a 21mm wrench to change a tire on a late model f-150; this is a great way to round a 13/16" fastener. No sale for me. Rant over.
