Hello, I work as a local mechanic at a dealership. Over the years I've seen SEVERAL common lug nuts loosen easily, including a few nuts from McGaurd and other common brands. All you have to do is take what's called a wheel nut puller (a gear nut) and drive it into the nut with a hammer and zip and you've just lost a wheel. BUT I like this one because it's a lot harder to get the extractor to grab the outside of the nut.
