Kyosho Mini-Z MR-015 2mm Aluminum Lock Nuts (Black) by 3Racing 3RAC-N20/BL/V2  [3RAC-N20/BL/V2]

2mm aluminum lock nuts for Mini-Z

This 3Racing 3RAC-N20/BL/V2 item is a set of 2mm aluminum lock nuts finished in black, designed as an RC-scale hardware replacement for Kyosho Mini-Z platforms. The parts are intended to match thread size and function used on Mini-Z MR-015, Mini-Z AWD, MR-01 and MR-02 (MM) variants where a 2mm lock nut is required.

Use notes: these nuts serve to hold wheel hubs and related hardware in place while minimising loosening from vibrations common in small-scale racing. Install with the correct 2mm tool, check thread engagement before final tightening, and avoid overtightening to prevent thread damage to alloy components.

Tuning role: swapping to lightweight aluminum lock nuts can reduce unsprung mass at the wheel assembly and provide a uniform finish for maintenance checks, helping with quick inspections between practice runs or events.
