The Axle Nut Washer & Split Pin is a small yet crucial component in any trailer wheel assembly. Designed to secure your hub assembly in place, this combo ensures safe, reliable operation under both light and heavy towing conditions.
Built for Durability and Strength
Constructed from high-quality galvanised steel, the Axle Nut Washer & Split Pin is built to last. The washer is designed to withstand heavy pressure from the axle nut without bending or warping, while the split pin securely locks everything in place.
Galvanising provides excellent corrosion resistance. This is especially useful for marine trailers or rigs frequently exposed to moisture, road grime, or saltwater.
Secure Fit for Peace of Mind
When towing, keeping your hub assembly secure is essential. The washer provides a smooth surface for the axle nut to tighten against, distributing pressure evenly. The split pin then threads through the castle nut and axle shaft to lock it in place.
This two-piece system helps prevent the nut from loosening due to vibration or wheel rotation. As a result, it reduces the risk of wheel wobble, hub damage, or catastrophic failure.
Easy to Install and Replace
Replacing your Axle Nut Washer & Split Pin is quick and simple. The washer slides onto the axle spindle right before the nut. Once tightened, the split pin fits through the pre-aligned castle nut and hole in the axle shaft.
You don’t need specialist tools—just pliers and a socket wrench. Even better, the parts are standard sizes, compatible with most trailer axles across Australia.
Ideal for Trailer Maintenance
Whether you’re replacing worn parts or performing a full hub service, these components are essential. They’re small, but they hold critical assemblies together.
For safety, always inspect your washer and pin when changing hubs, bearings, or seals. Bent, corroded, or damaged parts should be replaced immediately.
Keeping a few on hand in your trailer kit is a smart move, especially for frequent travellers or those towing heavy loads.
Universal and Reliable
Suitable for boat trailers, box trailers, and utility trailers, this set works across most axle types. It’s trusted by DIYers and professionals alike for its ease of use and reliability in harsh Australian conditions.
From highway hauls to boat ramps, you’ll want these parts doing their job without fail.
