These replacement nuts are of excellent quality, they were used in the cockpit of a 2016 F-150 xlt, do yourself a favor and get rid of the original nuts that Ford put on the two parts because you can ran into problems the other day when i tried to take them off and there is never a good time for this, it's a 21mm one piece head to put them on or take them off, they fit perfectly and look very sharp, only time will tell how they resist rust or corrosion I don't know yet but looks like they have a good chrome finish. I change my tires regularly. In a year I will check how they treat them in all four seasons. Good luck with your decision.
