Abstract

A one-piece insert fastener adapted for securement within an aperture in a panel by a threaded member. The insert fastener includes a base having a top surface, a bottom surface and a pair of outwardly protruding wings. In one embodiment, the base additionally includes a single-threaded, helical edge which is shaped to define an opening. In another embodiment, the base additionally includes an internally threaded drawn barrel which is shaped to define an opening. The insert fastener also includes a pair of resilient, spaced apart legs which are formed on and protrude out from the base. Each of the pair of legs includes an outwardly angled upper section, an inwardly angled middle section and a lower section. In use, the insert fastener is disposed into the aperture in the panel until the pair of wings abuts against the outer surface of the panel. The threaded member is rotatably driven into the opening in the base, the threaded member engaging the base upon rotation. Continued rotational driving of the threaded member causes the threaded member to contact and outwardly urge the pair of spaced apart legs into contacting engagement with the inner surface of the panel, thereby securing the insert fastener onto the panel. Insertion of the above fastener into a panel requires less than ten pounds of force. Once inserted, the fastener is secure until final assembly.
