These 17 mm long aluminum adapters convert a 4 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four M3 set screws for securing the adapters to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.
