Does exactly as it says and fits a normal 1/2" sq. drive perfectly. I bought it specifically for domed wheel nuts on my Austin Healy...good buy!

This is way to expensive and It does not fit a regular wrench. I was very annoyed as they didn't show an image of the top part of the socket so you did not know how big it was. It mentioned the dimensions but who's gonna get a tape measure and measure. Most people would believe any socket would fit any wrench.
