I must say that I have ruined nuts with sockets, but never ruined a socket with a nut.
I personally would consider that the socket failed in use, and should be warranteed. I expect that someone on this board works for Snap On, and could get this guy some new sockets, providing he was able to produce them.
Personally, I don't care one way or the other. My opinion is that if a company replaces a socket for a guy who has a 3,000.00 set of tools, they should replace one for a guy who has a hundred dollar set.
I have sets of sockets made before WW2 that are just fine thank you. But then I use an impact socket with an impact gun, and I use a 1/2 inch socket with a 1/2 inch breaker bar. I own a lot of Sears Craftman tools, mostly because they are easy to get, and if I break one, I just go to the store and get another. It has only happened a couple of times in the last 30 years. I keep doing business with them not because they have the best tools, but because they stand behind them.
This whole thread sounds like a bad joke.
Did you hear about the guy with the broken socket ? Tough Nuts.
These sockets are either covered or they are not. If they are not, you either pony up, or buy some other brand. Or you can keep pursuing it. In my world cheating is not an option.
