You used an impact socket on a torque wrench to tighten lug nuts?
No wonder it came apart! Those sockets are for impacting. They are very soft; so they won't explode from the impacting of your impact gun.
Get a set of chromes for torquing and a set of impacts for impacting.
I spent 20 bucks on a set of metric impact sockets from HF over 5 years ago, these are constantly beat on with an IR2135Ti that has been modified for even more impacting force, and these things are killer. I have never cracked or broken one.
