Left vs right hand thread wheel studs.

This thread is killing me! View attachment 1715369344

Yes its normal, and your thinking isn't screwed up.

Sometimes, but not always, there are markings on the nuts or the studs. Nuts will have a different color or line on them. Studs may have an L stamped on the head. One set of Crager closed nuts I have uses a different size hex for the lefties. They are easy to work with. All you have to do is run your clock backwards. View attachment 1715369345

And some chrome lugnuts have a groove machined into the hex.
