Pololu Aluminum Mounting Hub - 3mm (2 Stk.) - 2-56 Löcher
These universal mounting hubs are designed to work with most 3mm shafts, including round shafts, “D” shafts, and Tamiya’s 3mm hexagonal shafts.
Each hub has four mounting holes for 2-56 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. Each hub has four threaded mounting holes for #2-56 screws (not included).
The picture to the right shows a hub with one of Pololu’s mini metal gearmotors and a Pololu mini metal gearmotor bracket
