Frequently Asked Questions
How often should I torque my trailer wheel nuts?
Wheel nuts must be tightened to the manufacturer’s proper torque settings every 5,000 km or every six months. If you are actively touring in a caravan, it is highly recommended to perform visual checks every morning before setting off.
Why are these called “Holden” wheel nuts?
They are named after Holden because they perfectly match the historical stud threads found on popular Holden HT, HQ, and Commodore hubs, which are widely used across the Australian trailer manufacturing industry.
Can I use these on non-Holden trailers?
Yes. As long as your trailer hubs use 7/16″ UNF studs and require a 60-degree tapered seat, these wheel nuts will fit perfectly regardless of the hub brand.
