Muteki Lightweight Tuner Nuts (Open End, Silver) 12mm X 1.25RH
I replaced all 24 hub bolts and installed these things too
Maybe not for everybody, but they make getting the wheels on and off my truck
much easier now
The nuts are countersunk on my wheels and there's very little room in the well. I used to have to use a 21mm thin walled socket just to get the OE lugs on or off. These come with a large metal key making the process much easier, very cool.
