Abstract

A self-attaching nut having a central pilot projecting from an end face of the body portion, an annular groove surrounding the pilot and an annular panel support face surrounding the groove, wherein the outer side wall includes a plurality of circumferentially spaced notches, each having an outer wall which extends from the bottom wall of the annular groove to the panel support face and the bottom wall of the groove includes a plurality of circumferentially spaced radial ribs integral with either the outer or inner side walls of the annular groove having a radial end spaced from the opposed side wall and a top face inclined toward the bottom wall of the annular groove providing improved torque resistance and push-off strength. Alternating circumferentially overlapping radial ribs integral with the pilot and the outer groove wall and ribs which extend below the bottom wall of the groove are also disclosed.
