I would also say use a 19mm Socket with nylon protector on it as well... better safe than sorry.. no hydraulics either.. no need to chew things up.

A good quality socket the correct size with name-brand lug-nuts, hand torqued, and you don't need bother with nylon protectors.

A 19 mm socket is .748"; a 3/4" socket is .750; the difference is .002", hardly enough to be concerned about.
