Retain, or transmit torque?
Relying on set screws to transmit torque on an FRC robot is almost always a bad idea (except for things like potentiometers), but we've used them dozens of times to hold something in place (laterally along shaft) without any problems. That being said, I prefer to design around them, and either use Delrin spacers, stepped shafts, tapped shaft ends, E-clips, or roll-pins to avoid them. If we need to use them, we almost always drill for two set screw holes 90 degrees apart, use Loctite threadlocker, and only use the cone-tip set screws.
