A non-threaded nut came with the purchase of the first set. It was a "no-no" answer as it couldn't be bolted to the wheel. I returned this set and ordered another set hoping to get a better set. However, I was surprised to find that the second set is in even worse condition. Not only was one nut unthreaded, but some of the nuts had surface rust inside the nuts. The box it arrived in also looked like it had gone through a molt. Save time and money and avoid this product.
