RIVETLESS NUT PLATE, RIVETLESS NUT PLATE ASSEMBLIES, WORKPIECES CONTAINING RIVETLESS NUT PLATE FASTENERS, AND RELATED METHODS

摘要

The invention encompasses a rivetless nut plate that includes: a base plate having an inferior face and a superior face, a plurality of extensions for engaging a fastener, each of the extensions extending from the superior face in a direction substantially perpendicular to the superior face, the extensions defining a cage region between the extensions, and the extensions being adapted to receive a retainer for retaining the fastener against the superior face in the cage region, and an anchor comprising a body extending from the inferior face to a distal end, having a groove to contain a portion of a substrate that is formed about the anchor being disposed between the inferior face and the distal end and the body having a conformation that is not rotationally symmetrical about an axis perpendicular to the inferior face of the base plate.
