Holden Chrome Wheel Nut 7/16" x 5

Mag wheel nuts are also known as dome nuts, lug nuts, or acorn nuts. In addition to aesthetics, mag wheel nuts serve a practical purpose: they protect the end of the stud thread. Most trailer hubs are supplied with open-ended wheel nuts, which will lock onto your stud if they become rusty. This makes standard nuts impossible to remove with a standard wheel brace, and you will likely need a strong impact rattle gun. Mag wheel nuts with a closed-end are a better option for trailers, caravans, and campers operating in marine and/or off-road environments. 7/16″ UNF trailer wheel nuts are often used for Holden HQ, HT, and Commodore wheel stud pattern.
