Restraining bolt

"Fit him with a restraining bolt and take him back to His Excellency's main audience chamber."

- EV-9D9, regarding C-3PO

Restraining bolts were small, cylindrical devices that could be affixed to a droid in order to limit its functions and enforce its obedience. When inserted, a restraining bolt restricted the droid from any movement its master did not desire, and also forced it to respond to signals produced by a hand-held control unit. Some droids felt sheer horror at the mere mention of restraining bolts.
