SUMMARY
The discussion focuses on the forces acting on a bolt when it is screwed into a blind hole and bottoms out. When torque is applied, the bolt's threads exert a reaction force on the threads of the structure, regardless of whether the bolt bottoms out or not. If the bolt does not bottom out, the head of the bolt contacts the structure, initiating a different force interaction. However, if the bolt does bottom out, the bottom of the bolt contacts the hole's base, continuing to exert a pushing force on the structure as torque is applied.
