These Pololu 17mm long aluminium adapters convert a 3mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels.

These light-weight aluminium shaft adapters convert a typical motor output shaft into a 12 mm hex shaft that is compatible with many common hobby RC wheels, such as our 65mm x 25mm RC-style wheels. The side of each adapter that mounts to the wheel contains a hole tapped for M4 screws, and the other side of the adapter mounts to a motor shaft with two M3 set screws.

This set includes a pair of adapters, two 8mm M4 screws, four M3 set screws, and one 1.5mm Allen wrench for use with the set screws.

This version of the 12 mm hex adapter is 17mm in length and designed to work with 3mm diameter output shafts, including round and “D” shafts. It works well with our Micro Metal Gearmotors (as shown in the images) and Mini Plastic Gearmotors, as well as the other 3mm shaft gearmotors. The wheel shown in the above picture is a hobby RC wheel that works with 12mm hex shafts.
