Abstract
A cage nut assembly includes a nut having a cylindrical portion extending from a plate portion. The nut is encaged in a cage such that the cylindrical portion extends through an aperture in the cage. The cylindrical portion of the nut is collapsible such that the nut collapses and provides a plurality of flanges upon an application of force. The flanges are folded or curved/mushroomed such that the plate portion of the nut is suspended within the cage so that the nut will not, or will minimally, stick to the cage or workpiece when coated with e-coat or ELPO. Upon torqueing a fastener into place, the flanges are bent up to allow the plate portion to interface with the cage or a workpiece to provide a solid joint.
