1/2-inch UNF Extra Long Chrome Trailer Mag Wheel Nut
Upgrade your trailer’s reliability and style. This extra-long chrome dome nut protects your stud threads from rust, making wheel changes easy in harsh marine and off-road environments.
Product Description
Standard trailer hubs usually come with open-ended wheel nuts. Over time, exposure to salt water and mud causes these open threads to rust and lock solid. When this happens, removing them with a standard wheel brace becomes impossible, often requiring an industrial impact rattle gun.
The Couplemate™ 1/2-inch UNF XL Chrome Mag Wheel Nut (also known as a dome, lug, or acorn nut) solves this problem. Featuring a fully closed-end design, it seals the end of the stud thread against water, dirt, and salt. It is the ideal choice for boat trailers, caravans, and camper trailers operating in rugged environments. Commonly supplied to suit the popular 5 x 114.3mm PCD (Ford) hub pattern.

Frequently Asked Questions
What is the difference between a mag nut and a standard nut?
Mag nuts (dome nuts) have a closed end that covers the wheel stud. Standard trailer nuts are open-ended, leaving the stud thread exposed to dirt and water.
Why should I use XL chrome dome nuts on a boat trailer?
The closed-end design stops saltwater from rusting the stud threads. This ensures you can easily remove the wheel with a standard brace during a roadside emergency.
Will this nut fit my Ford trailer hub?
Yes. These 1/2-inch UNF 20 TPI nuts are the standard fitment for 5 x 114.3mm PCD Ford trailer hubs.
