one suggestion to that, besure to use a drill press or other machine tool to get the tap perfectly straight or you will have trouble with lug nuts and holes in the wheel lining up..with steel wheels and short bolts, not that critical, but if you have alloy wheels that need a stud 1 1/2 to 2″ and uses a shank style lug nut that goes into the wheel a 1/2 to 3/4 of an inch you will have an issue..I know that because when I first got my current car that was the first think I had to fix. when you install new studs with a knurl use the wheel and lug nut to pull the stud through straight
