THANK YOU ALL FOR YOUR CONCERNS AND SORRY FOR THE CONFUSION BUT HERE GOES:

DENIS: I DON'T HAVE A DIGITAL CAMERA, SO NO PICS;
SHERWOOD: THE NUT AND STUD WERE BOTH TURNING UNTIL THE STUD IMPACTED ON THE COOLING FIN BELOW AND STOPPED, THE NUT CONTINUED TO TURN, THUS THE STRIPPING;
JACK: THE WASHER WAS INSTALLED.
ALL ELSE WHO ARE INTERESTED IN THIS UNUSUAL CIRCUMSTANCE:
NORMALLY, WHEN A STUD (WHICH IS THREADED ON BOTH ENDS SEPARATED BY A SEGMENT WITHOUT THREADS) IS IMBEDDED INTO A PART, IN THIS CASE THE HEAD, IT WILL ONLY SCREW IN TO A CERTAIN POINT, THAT POINT BEING WHEN THE THREADS STOP. WHEN I TORQUED THE NUT TO 80% OR SO, THERE WAS NO PROBLEM. WHEN I TRIED TO TORQUE TO THE FINAL 100%, IT NEVER TORQUED, SOMEHOW. NOT HAVING SUCCESS REACHING THE TORQUE VALUE AS ONE WOULD HAVE EXPECTED, I BACKED OFF THE NUT, LOOKED AT THE STUD (APPEARED FINE), REINSTALLED AND AGAIN TORQUED THE NUT (W/ A SOCKET). THIS TIME, APPARENTLY, THE STUD TURNED RATHER THAN THAN THE NUT TIGHTENING. AS THE STUD TURNED (SOUNDS LIKE A SOAP OPERA), IT SCREWED INTO THE HEAD, UNTIL IT PROJECTED OUT THE UNDERSIDE AND IN CONTACT WITH THE COOLING FIN BELOW, THEN STOPPED. NOT KNOWING WHAT IN BLAZES WAS HAPPENING, I CONTINUED TORQUING IN UTTER PERPLEXITY. SAYING TO MYSELF, "WHAT, IN BLAZES, IS HAPPENING? (PARAPHRASED, OF COURSE) SOMETHING IS AMISS." AND SOMETHING WAS INDEED AMISS. I HAVE CONCLUDED THAT THE STUD FAIRY (NO PUN, HERE) INTERVENED AND SOMEDAMNEDHOW, THE TORQUE VALUE AT 80% WAS ENOUGH TO TIGHTEN THE NUT, BUT THE TORQUE VALUE AT 100% WAS JUST ENOUGH THAT THE STUD TURNED, NOT THE NUT (THE STEEL NUT, NOT THE NUT WITH THE TORQUE WRENCH, THAT NUT BEING MYSELF). MY NEXT QUESTION IS, "WHY DOES IT TAKE TWO PEOPLE TO SCREW IN A LIGHTBULB?"
