KYOSHO Mini-Z MR-015 / MR-01 2mm Aluminum Lock Nuts (Purple) by 3Racing 3RAC-N20/PU/V2  [3RAC-N20/PU/V2]

These 2mm aluminum lock nuts are a drop-in replacement for the small fasteners used on Kyosho Mini-Z MR series cars, supplied in a purple anodized finish for visual matching. Built as a scale RC accessory, they focus on retaining threaded connections where vibration and frequent assembly need reliable locking without adding bulk.

Use them where standard 2mm nuts appear on wheel hexes, suspension linkages, or small chassis brackets. The aluminum body reduces weight compared with steel counterparts while the locking feature helps prevent loosening during short course runs or club track sessions.

Installation is straightforward, tighten evenly without over-torquing and check thread engagement and clearance against nearby parts. As with all Mini-Z parts, confirm fit on the target MR chassis before extended use and inspect periodically for wear or damage.
