12mm Hex Wheel Adapter for 4mm Shaft – Pololu 2684

These light-weight aluminium shaft adapters can connect a typical motor output shaft with a 12 mm hex shaft that is compatible with many common hobby RC wheels. Each adapter features an M4 tapped hole on the side of the adapter that fits to the wheel. The motor side of the adapter has two holes tapped for M3 set screws as well as the hole for fitting a 4mm diameter output shaft. This model is designed to work with both round and “D” shafts.

Possible motors that could be used are 20D mm metal gearmotors (as shown in the picture above)* or 25D mm metal gearmotors. The wheels used should be compatible with a 12 mm hex shaft.

*Motor and wheels are not included in this set.
