I disassembled one last night and the confirmed what you said. I took a look on Aliexpress and it appears that 200mm and 300mm stepper motors (ie. T8 lead screws attached) are fairly inexpensive, so no need to remove screw from the motor. Just need to confirm the model with the correct motor height (40mm ) and pitch.
Cheers!
FYI I am using this motor to build a portable macro photography rig.
