Pololu Universal Aluminium mounting hub for 4mm shaft, 4-40 holes (pack of 2)
These universal mounting hubs are designed for most 4mm diameter shafts, including round shafts and "D" shafts. Each of the two supplied hubs has four #4-40 screws mounting holes (not supplied) so you can mount custom or mechanical components on your motors. The two supplied #4-40 hexagonal bolts (one for each hub) provide a secure connection between the shaft and hub, and a 0.05“ hexagonal wrench (often the smallest size in SAE hexagonal bolts) is included for use with the set screws.
