Essential 3mm Aluminum Nuts for RC Maintenance

When you need reliable small fasteners, the Tamiya 53021 - 3mm Aluminum Hex Nut Set is a practical pick. These aluminum hex nuts are built to be light while remaining tough enough for many RC uses, from chassis fastening to accessory mounts. They work well for routine servicing and for drivers wanting low-mass hardware during setup changes.

Yes, they are commonly used on off-road models, but check whether critical load points might be better served by steel fasteners if extreme shocks are expected.
Aluminum is less prone to rust than raw steel, though it can oxidise; regular cleaning and drying after wet runs helps preserve finish and fit.
You can reuse them while threads remain clean and undamaged, but replace any nut that shows rounded edges or compromised threads to avoid failures.
