A fastener assembly for attaching a seat back to a seat bottom forming a part of a recliner mechanism. The seat back includes a plurality of apertures defined therethrough. The seat bottom includes a pivotally engaged and extending arm having a first side and a second side and to which the seat back is engaged. The fastener assembly includes a substantially cup shaped spacer having an inner annular rim defining an open interior. A multi-sided nut is provided having an enlarged and substantially annular shaped end portion integrally formed therewith. A polygonal recess is defined through the lower seatback arm and matches an exterior configuration of the nut to permit insertion of the nut through the recess and so that the enlarged annular portion abuts against the first side of the arm and the nut extending beyond the second side and through the inner annular rim defined in the spacer. Edge portions of the nut associated with boundaries established between each pair of adjoining sides are then shear against cup spacer and to secure the nut and spacer to the arm. Upon aligning the apertures in the seat back with the assembled nut and cup spacer secured to the extending arm, bolt fasteners engage the seat back to the seat bottom.
