The one time I used a machine bolt (Socket Head Cap Screw, 10-32, 2", Black Oxide Steel) as a set screw, I completely destroyed the tip (the metal in the bolt was too soft).

I guess we have different anecdotes then. We've never had a problem with machine bolts as set screws on a flattened face in either FRC or FTC.
We used machine bolts on the inner rail shaft collars of FTC 354's champs-winning robot last year. They worked fine, even with the super high-traction wheels.
