Want to give your Ford Super Duty a seriously aggressive look? Check out this complete set of 32 black spike lug nuts! They're made from tough SCM steel and finished in a sleek black. The thread size is M14x1.5, which is standard for many Ford F250 and F350 wheels, and they have a 60-degree cone seat. The spikes themselves are 4.5 inches (115mm) tall, with an overall diameter of 0.9 inches. They use a 7-spline (3/4-inch hex) drive, so you'll need the matching key that's included in the set to install and remove them. The part number is 7-SP5454B, and they come brand new in the package. Whether you're going for a monster truck vibe or just want some standout wheel hardware, these lug nuts will definitely turn heads. Just make sure your wheels have the right seat type and that you're okay with the extra length sticking out!
