If you run a Kyosho Mini-Z MR-02 and want reliable fastenings, the 3RACING 2mm blue aluminium lock nuts are a practical upgrade. They balance low weight with secure clamping for everyday and club-level use.
Aluminium lock nuts lower the weight penalty of steel alternatives while still offering solid hold for small RC assemblies. The blue anodised finish offers extra surface protection against grime and moisture.
These lock nuts are manufactured to match Kyosho Mini-Z MR-02 specifications, ensuring a tight fit on wheel studs and key mounting points. Correct sizing helps preserve predictable steering and cornering response.
