The set includes one Allen wrench and two 4-40 set screws for securing the hubs to motor shafts.

These universal mounting hubs are designed to work with most 5mm 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.
