Left vs right hand thread wheel studs.
This should clear this up.
Look at your left hand, it should be on the end of your left arm.
Spin around a few times and stop in a different position. Look at the end of your left arm. Your left hand should still be on it ! Same would be true if you did this while on your head spinning. Left is always on the left and right is always on the right, unless I'm wrong !
