Abstract
A novel captivated jackscrew structure is characterized by the formation of both an internal cavity ( ) within one of the two bodies that are to be connected together and an access passage ( ). One end of the cavity, located at one end of the body is open. The small diameter access passage extends through the other end of the body into the cavity's other end. A standard machine screw ( ) is installed head ( ) first and captured within the cavity, with the screw shaft ( ) protruding from the end of the body ( ). A barrier ( ) is provided to prevent withdrawal of the machine screw head, but permit the screw head and shaft to move a limited distance axially within the cavity. A backstop ( ), resembling an inverted cup with a hole in the bottom lies in inverted position in the cavity over the screw's head.
