Cross thread once, it'll happen again, under your current setup. Go to Summit Racing and get some ARP -100-7723 wheel studs, 5 studs per pack. Also change out your lug nuts, maybe go with some Dorman 1/2-20, get 10 per box. Cheap products influence cross threading. Also, a Wheel Stud Installer, from Summit Racing, makes installing studs sooooo easy. Be sure to use Anti-Seize. Thread Chaser/Cutter is a good idea too, if you take off and put on wheels a lot.
