HEY
I'M TRYING TO DO UP SOME CALCULATIONS FOR TORQUES ON SCREWS GOING INTO HELICOILS.
I'VE DONE CALCULATIONS FOR SCREWS WITHOUT HELICOILS USING MACHINERY'S HANDBOOK ED.26 TORQUE WITH LENGTH OF ENGAGEMENT.

CAN I THINK OF IT THE SAME WAY..THE SCREW, EXTERNAL THREAD GOING INTO THE PARENT MATERIAL WHICH IS NOW THE HELICOIL (INTERNAL THREAD)....
I'M MISSING SOMETHING BUT CAN'T PUT MY FINGER ON IT.
