This is a replacement for M14 x 1.5 Ford nuts on my 2016 F150. The originals were swollen and difficult to remove, so I settled on a PC. strong nut. I was tempted to try the cheaper brands but decided to spend the extra money, mostly because of the solid reviews on the Ford forums. I've bought cheaper brands of cars with hubcaps and they have worked fine. I am concerned about rust as it shows up on my F150. They have fine quality control for fit and finish. Let's see if they live up to their reputation and hold up rust. I will check the MI after our winter and see how they perform.
