I'd take hex over round 99 out of 100 times for transmitting torque, but I don't agree with a blanket statement that says hex is always the way to go, especially considering budget. It's undeniably cheaper to drive a McMaster Carr Sure-Grip wheel with a round shaft than a hex shaft.

Putting a hex in a 1.25" hardened steel worm is impossible for most teams that don't have access to a wire edm. Using a keyed shaft would be a better solution, especially if there isn't room in the worm for a 3/8" hex.


If you have a set of two driven rollers or wheels with a pair of bearings in between, you're forced to use a hex bearing here. The inner race of the hex bearing is much weaker than the inner race of the round bearing and has a sloppy fit. I'm pretty sure 254 solved this problem in the past on their outer wheels by using 1/2" keyed shaft...
