Torque Needed for Loosening defines the minimum amount of torque that must be applied in the reverse direction to successfully loosen the screw.
Here's how it works:
If this parameter is set, the user cannot simply rotate the screw backward to remove it.
A tool (like a torque wrench or drill) must apply at least the specified torque in reverse to initiate loosening.
This simulates real-world conditions where fasteners are tightened to a degree that requires force to undo — for example, screws with thread-lockers or those under tension.
