Shank & Lug Nuts

Nuts for Steel & Alloy Trailer Wheels
Wheel nuts are an important part of your trailer and caravan mobility group.

Nuts secure your wheel to your axle or independent suspension hub. As a guideline, we recommend tightening your wheel nuts to proper torque specifications every 5000km or 6 months.

Couplemate™ sells two types of high-quality wheel lug nuts which suit a variety of caravan, camper, and general trailer applications. These are:

Open-Ended Hex Nuts
Dome Mag Nuts

The most popular style of wheel nut is an open-ended nut. Dome mag nuts are best for off-road and marine trailers as they protect stud thread from rust.

One easy way to monitor your wheel nuts is through wheel nut indicators. Though often used on trucks, these indicators are practical for long-distance trips with your caravan and camper trailer.

Moreover, they suit a wide variety of trailer applications.
Suit Popular Stud Patterns
Couplemate™ offers a range of wheel nuts for popular and niche trailer and caravan wheel stud patterns. Ensure you check knurl thread on your wheels for an easy replacement.

The most popular PCDs and Threads include:
