Abstract : This invention pertains to a screw-nut mechanism for clamping two work pieces together. In one application the mechanism is used to clamp a cover plate over an access opening in a vehicle hull or similar member. The screw-nut mechanism is specially designed for use where one face of the hull or similar fixed work piece is inaccessible for welding or otherwise affixing the nut on the concealed face of the inaccessible work piece. I provide a screw-nut mechanism that avoids the necessity for affixing the nut to the work piece. In my invention the nut is a loose hardware item that can have a thread length proportional to the expected load, thereby avoiding strength problems associated with the formation of threads directly in relatively thin work pieces.
