Screwed! (can't uncrew)
Gents, I recently acquired an old car with these "security" lug nuts. Well, they are secure. They have a six pointed star cut into the center of the nut, into which a special socket is designed to fit. The nut is also conical, it tapers slightly from the base to the outer end. I tried one of these kits that threads a reverse-threaded socket onto the outside of the nut, but the steel of the nut is too hard and the tapered shape thwarts the effort as well. Where might I find one of the designated sockets or something else that would work?
