12×1.5 correct?

im assuming i can grab these out of a parts bin at auto parts store.. anyone know what actual vehicle shares that stud?

i changed studs in a civic before, 12×1.5 but the guy at auto parts store (probably wrong and retarded) is telling me 12×1.5 could be a lot of different ones. (whereas i thought 12 was the diameter of bolt and 1.5 was the pitch of the threads)

also.. the nuts… are they conical or tapered seat? the machine is missing it’s wheel/studs in the woods so i dont have it on hand to check.
