Oh geeze, yeah - CAD plated fasteners are still part and parcel of building airplanes and, of course, repairing them. Grip length is, of course, far more important than what we allow on our cars and such - no threads in shear under any circumstances. We don't like to stack many washers, either, so things can get "interesting" when we are repairing things. I well remember mechanics holding CAD plated fasteners with a pair of vice grips and cutting them with a cutoff wheel in a die grinder, then painting the exposed end with green SRF primer. Then going to lunch. Without washing their hands...
