  • Screw and nut assembly
    Patent number: 5855460
    Abstract: A screw and nut assembly comprises a screw having a hollow cavity extending longitudinally throughout, a nut configured to screw onto the screw, and an extension attached to the nut. The extension traverses the hollow cavity of the screw when the nut is placed on an end of the screw without being screwed on. The extension is displaced from the hollow cavity of the screw as the nut is screwed onto the screw. The status of the screw and nut connection may thus be determined from the screw side of the assembly, without observing the nut, by observing the extent to which the extension has emerged from the hollow cavity in the screw.
