These universal mounting hubs are designed to work with most 4 mm shafts, including round shafts, and “D” shafts. Each hub has four mounting holes for 4-40 screws (not included), letting you mount custom wheels or mechanisms to your motors. 4-40 hex set screws (one included for each hub) allow secure coupling of shaft to hub. A 0.05" hex wrench (often the smallest size in SAE Allen wrench sets) is included for use with the set screws.

The picture to the right shows a hub with Pololu’s 25:1 metal gearmotor 20Dx44L mm and a Pololu 20D mm metal gearmotor bracket. This hub will work with any Pololu 20D mm metal gearmotor.
