This set contains four 2mm non-flanged lock nuts machined from aluminum 6061 for use on Kyosho MINI-Z MR02 micro RC assemblies. They provide a metal retaining option where nylon or flanged nuts are not suitable, improving durability for repeated disassembly and precise stack-up in tight spaces.
These parts are intended for the Kyosho MINI-Z MR02 platform; confirm the 2mm thread pitch and available clearance on your MR02 hubs or wheel carriers before fitting. The non-flanged profile reduces interference with nearby components and helps achieve a flush installation in close-tolerance areas.
Installation notes: thread the nut onto the correct 2mm fastener until it seats with slight resistance, then apply a short additional turn to lock. Avoid over-tightening which can strip fine RC threads, inspect mating parts for burrs, and replace any damaged hardware to maintain reliable connections during running.
Tuning and maintenance role: replacing plastic or flanged nuts with these aluminum lock nuts will change component stack height and can speed regular servicing. Choose them when a compact, durable metal fastener is required for frequent maintenance or when flange profiles interfere with suspension or wheel geometry adjustments.
