Brass hub kits for connecting 12mm hex fitment wheels (RC-style wheels) to motors! All of our brass motor shaft hubs look almost identical but have different sized motor shaft diameters ranging from 3mm to 7mm.

Please measure your motor shaft size carefully before buying these hubs.

This is a 7mm hub, good for use with motors with a 7mm shaft and 12mm Hex fitment wheels.

The hubs feature a motor shaft input hole on one end, and a 12mm hex and M4 screw point for fixing on the other. Most 1/10 scale RC wheels are 12mm hex.

Coupler and screws only.
