This point is kind of interesting. It would seem to me that the threads
have to start recessed down in the hole. Otherwise, there would be no room for the shoulder on the bolt. It is the shoulder on the bolt (and not so much the threads) that guards against the 500 ft./lbs. of twisting force. The tip sheet on my clutch points out in large
BOLD letters:
"You must use shoulder type bolts to mount the pressure plate to the flywheel. This will keep the clutch aligned properly on the flywheel and increase the shear strength. Please do not use the improper bolts as you will be endangering your safety as well as affecting the balance of the assembly." http://www.centerforce.com/mediafiles/I92FO002.pdf
