I would not take a chance on not using Nuts made for the Job.
The Upper large Nut has a handed tip on it and the lower one is thinner that a regular Nut.
Also on My Year and Model the Valve Rotates. So you don't want anything giving because it is too soft and then having the Valve Rotation turn the Nuts.
