NHRA says the diameter of the stud must stick out past the lug nut seat on the wheel. So in your case you need 1/2" of stud protruding past the top of the lug nut's seating surface or the top washer in installed.
Or as NHRA states" The stud must protrude into the hex portion of the nut at least the diameter of the stud.*"
