Abstract: The nut apparatus is formed by a body member having two ends with a threaded aperture extending therethrough between the two ends for receiving the threaded shank of a bolt or the like. The body member has a tapered portion at one end for partial insertion into an aperture formed through the structure of the toilet through which the bolt is to extend. An arm extends from the body member at a position between the base of the tapered portion and the other of the two ends of the body member transversely to the axis of the threaded aperture for engaging structure of the toilet to hold the body member stationary while the bolt is screwed into the threaded aperture or unscrewed from the threaded aperture. The body member, the tapered portion, and the arm are integral with each other and are formed of a suitable soft plastic material. A scored line extends across the width of the arm to facilitate breaking of the arm at the scored line to shorten the arm if desired.
