Torque wrench socket for lug nuts

Hello all. It's about time for me to replace the original brake pads in the front. And I figured that I'm gonna to this myself because of the absurd prices at the dealer. Anyway, I'm just gathering my materials now, and I'm at the point of looking at torque wrenches. I just have one issue. I'm looking at this 1/2 torque wrench, but can't seem to locate a socket for our cars lug nuts. A little digging around the forums reveal that we have 14x1.5 lug nuts, but I guess that doesn't translate to the hex size? I'm not the type of person who can just look at a bolt and know what size it is. I mean, I can just go without a torque wrench, but I kind of want to make sure it's done correct.
