I bought 10 Dorman lug nuts for my 2012 Chevy Equinox. After installing them on my car, I bought the remaining 10 so I would have new nuts all over my car. My original nuts started to rust after 7 years and over 150,000 miles. The new Dorman nuts looked good and seemed like a great replacement. The first 10 started to rust within 2 weeks and now the other 10 I bought are starting to rust. They are recommended as a suitable replacement on many websites. I learned my lesson the hard way. I just had to order $140 genuine OEM Chevy nuts for 20. STAY AWAY from those Dorman Nuts.
