Overview

These light-weight aluminum 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 the Dagu Wild Thumper 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 8 mm M4 screws, four M3 set screws, and one 1.5 mm Allen wrench for use with the set screws.

The adapters are available in the following versions:

• 12 mm Hex Wheel Adapter for 3 mm Shaft (17 mm length)
• 12 mm Hex Wheel Adapter for 4 mm Shaft (17 mm length)
• 12 mm Hex Wheel Adapter for 6 mm Shaft, Extended (35 mm length)

Details for item #2682

This version of the 12 mm hex adapter is 17 mm in length and designed to work with 3 mm diameter output shafts, including round and “D” shafts. It works well with ourMicro Metal Gearmotors (as shown in the picture above) and Mini Plastic Gearmotors, as well as the other 3 mm shaft gearmotors we carry. The wheel shown in the above picture is a hobby RC wheel that works with 12mm hex shafts; we do not currently carry this wheel or any other wheels that are compatible with this adapter.
