Technical screw thread length
I don't know "the answer" but...........
My car came with steels, but they lasted less than 48 hours before the alloys went on. ( Before her indoors noticed they were steels ). My fitter used the same bolts, saying the thread length didn't matter, but the angle of the cone was important. Comparing the steel and alloys, I'd say they hold the bolt off the hub near enough the same amount, no more than a mm or two in it.

If you're really worried count how many turns in you can put the bolt without it rubbing against something with the wheel off. Then make sure you don't wind it in more than that number of turns with the steel wheel on.
