*Update. After only a few months in Iowa weather they start to rust.** Ring nuts appear to be of decent quality with good chrome and finish. Fits my 2014 Jeep Patriot Latitude 4x4. The original factory jam nuts actually have a 19mm cap on a 18mm steel jam nut. They're extremely cheap and the caps come off, resulting in a lot of people having to pull the lug nuts off and ruin the rim by removing them.
