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

These 2mm aluminum lock nuts are designed as a direct swap for the small fasteners used on Kyosho Mini-Z MR cars, finished in purple anodise for a neat appearance. They focus on keeping threaded connections secure where vibration and repeated assembly occur, without adding weighty hardware.

They are suitable for mounting on wheel hexes, minor suspension links and small chassis brackets that take a 2mm nut. Aluminum lowers mass compared to steel, while the locking mechanism helps resist loosening during short track runs or club races.

Fitting is straightforward: apply even tightening and avoid over-torque. Verify thread engagement and check clearance to surrounding components. Confirm fit on your specific MR chassis before long sessions and inspect for wear as part of routine maintenance.
