These aluminum lock nuts are intended as small replacement fasteners for Mini 4WD assemblies where a secure, vibration-resistant connection is required. The nylon-style insert helps resist loosening on roller shafts and mass damper posts, and the aluminium body reduces weight compared with standard steel nuts.
The parts are compatible with Mini 4WD PRO and standard Mini 4WD cars; they are intended for routine maintenance and part replacement rather than chassis-specific performance upgrades. Use common Mini 4WD fastening practice and check thread engagement to avoid damage to shafts or posts.
This five-piece set provides a compact, corrosion-resistant locking solution for securing rollers and mass dampers during maintenance and display preparation.
