What is this part called on the rear axle that slides into the wheel?

[Rocco1005]

On the rear axle of my Redcat Shredder theres a tiny little pin that broke that keeps the wheel from coming off. Can someone please tell me what the part is called that i would have to replace or can i just buy some of those tiny pins? It looks like that pin slides into some holes in the middle of the wheel to keep it on.

They are simply called pins, maybe you can measure them to be sure, most brands use 3.0x17mm pins, but you can order from the OEM here to play is safe:

I like to grind a small flat spot on the center of my pins to get more bite with the set screw, here's an example of the TEKNO pins:

Axle Pin or retainer pin. Goes through the axle to hold the axle in the bearings / hub. On some cars the wheel can be hold on by a nut on to the pin, or on a wheel hex. Wheel hex captures the pin and also secures the wheel.
