I decided to replace the stock nuts on my Ford Fusion with these after realizing that the factory nuts are complete crap. As many may or may not know, the factory nuts on many Ford vehicles swell over time and are almost impossible to remove with a spare tire kit should a flat tire ever occur. Their design is flawed in that they have a "cap" on top of the nut instead of being a solid one-piece nut. Now with that said, these nuts are one-piece solid nuts. They are of excellent quality at a good price and are almost identical in shape to the factory products. They fit perfectly and I've been happy with them since installation, although I haven't had to take them off since installation, but I doubt they'll have problems like the factory ones. I would recommend them to anyone looking to replace the factory.
