1/2-inch UNF Ford Chrome Trailer Mag Wheel Nut
The 1/2-inch UNF Ford Chrome Trailer Mag Wheel Nut, also known as a dome nut, offers both aesthetic appeal and essential thread protection for your wheel studs.
Its closed-end design is particularly beneficial for trailers, caravans, and campers operating in challenging marine or off-road environments, as it prevents rust-related locking issues commonly encountered with open-ended nuts.
With specifications including a 19mm hex, an overall length of 31mm, and a thread of 1/2-20, these chrome wheel nuts ensure a secure fit and reliable performance, making them an ideal choice for Ford vehicles.
Consider upgrading to the XL version for additional length if required.
Beyond aesthetics, mag wheel nuts serve a practical purpose: protecting the end of your stud thread.
Most trailer hubs are supplied with open-ended wheel nuts that 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 high-impact ratchet 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.
