Universal Mounting Hub, 4mm shaft, #4-40 holes

Pololu's universal aluminium mounting hub, from their own CAD: a 19.0 mm disc 5.0 mm thick with a 4.0 mm bore for a 4mm shaft and 4 holes tapped #4-40 on a 12.7 mm circle — which is the bolt pattern Pololu's own wheels carry. A set screw clamps it to the shaft, through 1 tapped M3 hole that break into the bore.

One of the Universal Mounting Hub family.
