Upgrade or replace your worn-out lug nuts with this set of 10 heavy-duty black lug nuts. They're designed specifically for Ford Super Duty trucks like the F-250, F-350, F-450, and F-550 (always double-check fitment for your exact model and year!). These nuts have an M14x1.5 thread, are 0.90 inches long, and feature a 13/16\ (21mm) hex head with a flat seat. The big advantage? They're a solid one-piece construction, unlike some factory two-piece lug nuts that can swell or separate over time. Made from tough steel with a black finish, they resist corrosion and look great with black wheels or accents. They meet or exceed OEM standards and directly replace part numbers like 2C2Z-1012-AA and 611-246. Whether you're rotating tires, installing new wheels, or just want more reliable hardware, these lug nuts are a smart investment. They come in a pack of 10, which is usually enough for one wheel (if you have 8-lug wheels) or a full set for a car with 5-lug wheels. Keep your wheels securely fastened with these durable, no-nonsense lug nuts.
