This is a pretty handy product. For multi-stage custom gearboxes, this combined with the press-on 15T CIM pinion is a good way to squeeze a lot of reduction into less space. We have used it as the first reduction for robot arms and winches in the past. It is also a nice, quick-and-dirty 4:1 reduction for a roller or something.

The 3/8" hex dimension was closer to 0.378" than 0.375" and with the two effective countersinks at each end of the hex bore, the effective bearing surface for the 3/8 hex shaft is reduced significantly. There was a bit of wobble between the shaft and the 60T gear. We had to peen each side of the Aluminum hex shaft to get a nice press fit.
