I have a 2013 Ford F150 FX4 with stock rims. These lug nuts appear to be well built. Look out for "aftermarket wheels only". I didn't see that when ordering, I just stated "This product fits your 2013 F150". Yes, it does. Yes, but they are smaller in diameter than OEM, which in my case causes the tires to be unbalanced. Balanced all wheels 3 times, the problem remained. Haven't tried different nuts but visually I can see they don't fit as well as OEM nuts. So if you're looking for a replacement for Ford's rusty, swollen nuts on factory rims, this probably isn't what you're looking for.
