SnapOn does have a socket design they call "Flank Drive" which focuses the force on the flats of the nut more than the peaks. May not have made any difference in this situation. Cutting the heads off is the only way to go for this.The screws that get stuck probably haven't heard of your interesting theory. Even if there is a special anti-slip socket, it is possible to destroy a screw that is properly stuck.
Honda gives the tightening torque to the NUT (75Nm 55Lbf) and NOT the bolt.
But to release a pair of nut and screw, like in this case, it is better to go to the head of the screw and not the nut.
If I was installing them, I'd be using a socket on the nut anyway.
55 ft/lbs is a bit much for those nuts/bolts IMO. My son's Yamaha had larger fasteners that listed the torque at 70 ft/lbs - and he stripped them out.
I'd be careful using 55 ft/lbs on those.
