Mine are all on set screws. Had a crash a few months ago where the
cross-feed axis pushed the headstock out of alignment. The set screw did
fine in transmitting the torque necessary for that. No damage apparent to
anything, good for me.

Berg. I can't think of one single place I'd trust more for quality and
the cost wasn't bad either. They make a wide variety of sizes and types.
I'm driving from 450 and 600 oz/in steppers with belts rated at 100 lbs
tensile and about 5/16 wide.

Best wishes,
