So here are the problems and I've attached 4 photos1. The socket marked with the picture and the auto shoulder socket clearly show that your socket provides approximately 30% less bearing coverage on the nut than the wrench socket supplied with the vehicle. This is a BIG problem 2. The image labeled as a loose fit shows that loosening your socket means quite a bit for the lug nut compared to fitting the car key socket and this is a BIG problem3. The picture labeled "bent bar" shows the bent bar from my first use to loosen a jam nut. The 1/2 inch rod should never bend.
