Metric wheel nuts or wheel lugs are made to meet SAE standards and have a zinc, chrome or stainless finish.
Open and closed wheel nuts are interchangeable. When replacing your wheel nut, match the thread size, seat type and hex size to your original.
Optionally, a wheel nut with the same thread size and seat type but with a different hex size can be used, however a new matching hex size wheel nut removal tool is required.
Keep the tool in your vehicle for future or emergency use.
