These are lug nuts nothing to say they hold the wheels. Seriously, they look really good and other reviews show they hold chrome better than cheaper brands. I had to transplant them to new rims (tighten after a few miles), but I think that was just the result of two new finishes mating together. I had to wait for a short order, only needed ten for the trailer and this lot ran out, but it didn't take long and I'm glad I waited for it.
