Ok. I'll admit I'm confused. Where does it say 21mm socket? I thought the OEM was 13/16"? The Gorilla marketing page has multiple sizes depending on which product you buy 13/16" hex, 3/4" hex, 7/8" hex. Very confusing.@cooldude919
One more question, does the factory lug wrench fit the new Gorilla nuts? I see it says 21mm socket, but no idea what OEM ones are.

13/16" = .8125"
21 mm = .8268"
then there's this page that lists 13/16" and 21mm on same lug

I'm pretty sure my SK 13/16" socket would not fit on the Gorilla lug nuts I bought and I put a 21mm socket & breaker bar in the tool kit. Think it measured out with a micrometer to .823". Too confusing for my little brain.
