This pack of four M4 serrated flange wheel nuts is designed as replacement hardware for ARRMA remote control vehicles and helps secure wheels onto the axles by biting into the wheel surface to reduce loosening under load. The nuts are black and precision threaded to ensure a consistent fit on 4 millimeter wheel studs and long‑lasting performance in demanding driving conditions. Serrated flanges help improve grip and retention compared with standard nuts, making them useful for routine maintenance or replacing worn or lost wheel hardware. Having multiple wheel nuts in a set means you can outfit all four wheels and keep spares ready for future service
These Black M4 Serrated Wheel Nuts are constructed from super-durable material for long-lasting performance.
