I have a 2012 Ford Focus. On the nuts that came out of the car, there is a piece of plastic on top of the nut itself. One of the nuts was broken. So I decided to change them all so this doesn't happen again. These nuts don't have cheap plastic on the nut. They will last longer. I wish I knew the old Lunites are junk. My tire blew out on track and I was unable to remove the wheel to fit the spare wheel. I had to tow the car to a shop to have it removed. I urge anyone who has nuts with a higher plastic price than the nut to substitute them. This is a good product at a great price.
