Re: Lug Nuts
Something that hardly ever seems to get mentioned about the typical 5/8" wheel drive studs that a lot of us use is that the shoulder that fit's into and locates the wheel is actually 11/16" in diameter. This is the same diameter as the shank on a standard 7/16" or 1/2" threaded straight shank lug nut made for racing wheels. The 5/8" part of the stud is just the thread size. So if you want to use 5/8" drive studs, the holes in the wheels need to be 11/16" diameter. If the wheel is made for use with conical lug nuts it may not work with the 5/8" studs unless it's drilled out and has enough material left to bear on the stud without deforming under hard acceleration.
