Some years back I definitely got a bad batch of wheel studs from Z1. The knurling wasn't even close to being right though in my so I was able to catch it during the initial install of the studs.
Since then, if I ever have to replace a stud, I always confirm dimensions of the new stud(s) just to make sure.
