Pololu Universal Aluminum Mounting Hub for 6mm Shaft Pair, #4-40 Holes (2 pack)

Key Features:

• Mount custom wheels or mechanisms to your motors
• Universal mounting hub designed to work with most 6 mm diameter shafts
• Pack of 2 hubs

These universal mounting hubs are designed to work with most 6 mm diameter shafts, including round shafts and “ D” shafts. Each of the two included hubs has six mounting holes for #4-40 screws (not included), letting you mount custom wheels or mechanisms to your motors. The four included #4-40 hex set screws (two for each hub) allow secure coupling of shaft to hub, with the longer set screws intended for the deeper of the two set screw holes. A 0.05 ″ hex wrench (often the smallest size in SAE Allen wrench sets) is included for use with the set screws. A dimension diagram of the hub is available under the resources tab.
