A pushnut fastener for engagement on a cylindrical stud and particularly suited for conveying to the point of use through automatic feed systems comprises a metal body of relatively thin, uniform thickness having oppositely facing first and second exterior surfaces and a circular radial outer marginal periphery. A central opening extends axially through the body between the oppositely facing exterior surfaces and defines a generally circular inner marginal periphery having resilient finger-like engagement portions for engaging and gripping the exterior of the cylindrical stud. The finger-like engagement portions are inclined to extend laterally of the body outwardly of the first exterior surface a maximum distance of d. A circumferentially continuous cylindrical peripheral flange is formed on the radial outer marginal periphery to extend generally perpendicular to the first exterior surface and terminate in a continuous free end which lies entirely in a plane parallel to the first exterior surface outwardly thereof a distance D which is substantially greater than d. The outer free end is smooth and radiused on the radial inner edge. A relatively large transition radius extends completely about the radial outer marginal periphery between the second face and the circumferentially continuous peripheral flange.
