ABSTRACT:
A one-piece molded plastic nut for receiving a screw adapted to retain a trim assembly to a panel having a slot. The plastic nut has a head having a bottom surface and a top surface with a trench molded into the head and opening onto the top surface. The trench has a bottom face with three holes molded in the bottom face of the trench that extend through to the bottom surface of the head with the holes adapted to receive the screw. The trench has a pair of opposing facing planar side walls and a pair of opposing facing planar end walls angled towards the bottom face for guiding the screw towards one of the holes in the bottom face. Two flexible webs are spaced between the holes and conform to and engage the screw when inserted into one of the holes. A pair of legs mirror each other and are adapted for insertion into the slot for engaging the panel and retaining the plastic nut to the panel. Each leg has an inner surface having a series of molded curved surfaces aligned with the holes in the head. These curved surfaces allow the screw to extend between the legs creating an interference fit with the legs, retaining the legs against the panel adjacent to the slot whereby the trim assembly is secured to the panel by the screw which is guided into one of the holes by the planar walls.
