Yup, that's the downside of purchasing surplus and/or remaindered items.
Eventually, they go away. If the steppers you're referring to were part
of a surplus tape head positioner assembly at All Electronics, I picked
up a couple, myself. Good price for some miscellaneous fasteners,
springs, and a groovy stepper motor and lead-screw combination (sorry
for the lame pun).
It looks like
<http://www.allelectronics.com/make-a-store/item/SMT-102/STEPPER-MOTOR-W/-SCREW-MECHANISM/1.html>
is *possibly* a similar actuator.
