Here are before and after shots on stock (4-yr-old) rims, sorry these are sideways (turn your head to view...LOL):

Some of the lug nuts were frozen to the threads. The bulged (internally oxidized) made these a real PITA to remove. I had to use combinations of 19mm, 20mm, and 3/4 inch sockets (and some hammering) to get them off and then to get them out of the sockets. Best and worst case below:

The damage to the one on the right was from using a punch to get it out of the socket... But it shows the idiotic two-piece construction of the OEM nuts.
Took me an hour to do three wheels... Two of the lug nuts were downright awful since they were both overtightened and nearly rounded off.
Bottom Line: If you're running stock lug nuts, get these changed out before you get stuck on the side of the road with a flat.
