For builders focused on weight and reliability, the 3Racing 3RAC-NF40/GO 4mm aluminium flanged lock nuts are a practical choice. They fasten securely while adding a neat gold accent to exposed hardware. The aluminium body keeps unsprung and rotating weight to a minimum for nimble handling.
Crafted from aluminium, these nuts balance corrosion resistance and lightness. The gold surface improves appearance on customised models and helps distinguish upgraded hardware from stock parts. The flange provides a stable seating area to combat vibration-induced loosening.
Keep a set in your spares kit for track adjustments or routine repairs. These nuts are easy to fit with standard RC tools and work across a wide range of 4mm hardware applications on touring, on-road, and lightweight off-road models.
