Revain seller FALSE lists dimensions as SAE (US) "includes 4 different hex sizes: 11/16", 3/4 "", 13/16" and 7/8" (17, 19, 21 and 23 mm) with metric approximations in parentheses.

Sellers need to have at least some knowledge of the product they are selling so the buyer doesn't have to product that is not working properly, or worse, may result in damage or injury.
