These black Tamiya 4mm Serration Wheel Nuts are intended to deliver dependable wheel clamping on TRF-style hubs. The serrated bearing plane is designed to reduce movement between nut and wheel under stress.
The serrated bearing surface improves bite compared with conventional nylon nuts, allowing higher clamp force and steadier wheel positioning for competitive or hobby use.
Primarily developed with TRF chassis in mind, the nuts suit a variety of 4mm hub applications thanks to their robust steel construction and resistance to routine wear.
