Should be 1/2 x 20 for threading.

Are you asking about the stud size or lug nut size? The studs will be 1/2 X 20 BUT the serrated part of the stud will vary in diameter depending on whether or not the vehicle is 1/2 ton or 3/4 ton. The length of the stud will also vary, depending on application. I believe all lug nuts will be 1/2 X 20.

Rock Auto shows the different applications, based on size of truck.
