The Normal Depth parameter defines how far the screw is driven into the object — essentially, the insertion depth along its axis.
It controls the visual and physical movement of the screw as it is turned:
A higher value means the screw travels a greater distance into the material.
A lower value results in a shallower insertion.
This parameter is important for realism, especially when working with different screw lengths or materials. It directly affects how the screw behaves and looks during the tightening process in VR.
