| Pololu 20D mm gearmotor with bracket and hub. |

These light-weight brackets (under 5 g each) are specifically designed for Pololu's [20D mm metal gearmotors](https://core-electronics.com.au/components/motors/metal-gearmotors.html). Each bracket features three mounting holes and ten mounting slots (five along each edge) for [M3](https://core-electronics.com.au/machine-screw-m3-5mm-length-phillips-25-pack.html) or [\#4-size screws](https://core-electronics.com.au/machine-screw-4-40-1-4-length-phillips-25-pack.html), giving you a variety of mounting options. A total of four M2.5 screws (two for each bracket) are included for securing the motors to the brackets.

Pololu's [4mm mounting hubs](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-4mm-shaft-4-40-holes-2-pack.html) works nicely with this bracket.
