Abstract

A self-locking nut having an enlarged head and an elongated shank portion insertable into a hole in a panel. The nut has an integral skirt portion adjacent the underside of the head having a predetermined skirt length, which skirt is then deformed against the underside of the panel to hold the nut in firm position with respect to the panel. The nut may be provided with an irregularly shaped head conforming to a like configured countersunk in the panel leading into the hole to prevent rotation of the nut about its longitudinal axis.
