Replaced OEM jam nuts and looked great initially. It was about a year before I noticed that some of them were badly rusted. I bought black; Chrome can be very different. Also, don't forget to keep the socket in the car, otherwise the standard key won't help when changing tires. The spot where I change tires didn't have a suitable outlet - I had to borrow the one that came with the kit. They are serviceable, the tires stayed on the car even with rust - they were replaced 18 months from the date of purchase.
