If you're working on trailers, RVs, or boats, this axle nut kit is an absolute must-have for your toolbox! You get two complete sets that include everything you need for 1-inch shaft spindles - two inner nuts, two washers, and two 2.2-inch long cotter pins per set. The stainless steel construction is seriously durable and corrosion-resistant, which is perfect for marine environments or areas with harsh weather conditions. I've used these on boat trailers that see saltwater regularly, and they hold up way better than the standard steel components that rust out quickly. The threads are smooth and deep, making installation and removal much easier than some cheaper alternatives. The 2.2-inch cotter pins are long enough to work with easily, and you can trim them to the exact length you need for a perfect fit. Everything works seamlessly with original equipment - no modifications or forcing required. I keep a couple sets in my trailer maintenance kit because they're perfect for emergency repairs on the road. The quality is noticeably better than what you'd find at most auto parts stores, and having two complete sets means you can do multiple axles or keep spares for future use. Whether you're maintaining your RV, boat trailer, utility trailer, or caravan, having the right hardware is crucial for safety, and this kit delivers exactly what you need. Just double-check your spindle size before ordering to make sure 1-inch is what you need - but if it is, this kit will save you multiple trips to the hardware store!
