ABSTRACT:
The present invention is a separation nut for fastening and releasing a threaded bolt under remote or manual controls. The preferred embodiment of the present invention separation nut includes a housing, a base, a ramp which is fitted into the base, and a three-piece segmented threaded nut placed on top of the ramp and enclosed by a three-piece segmented spool, which is in turn bounded by a restraining wire. The three-piece segmented threaded nut and the three-piece segmented spool are held in place by a spring biased plunger. Anti-rotation pins are employed for preventing rotation of the segmented nut. A release pin is provided for inhibiting the restraining wire from releasing the segmented spool. The release pin is connected to a flexible shaft.
