ABSTRACT:
A combination of a plastic part and metal part functions as a fastener to attach a panel to the flange of a portion of a chassis for electronic equipment or the like. The panel is formed with a counterbored hole and has an arcuate groove outside the counterbore on the outside of the panel and angularly spaced dimples on the underside. The fastener is a peripherally flanged hollow cylindrical member fitting into the hole and counterbore. It has a partially closed bottom and opposed openings in the cylindrical walls. A detent slants upward-outward from the bottom through one of the openings. A metal clip attaches to the cap, having an inverted U-shape having a web and two depending sides which fit through the openings. The top has a shoulder which locks outside the detent to hold the parts assembled and has a locking extension beyond the shoulder. One of the sides has an arcuate arm approximately in the plane of the top having a dimple which engages the dimples on the underside of the panel to hold the fastener in positions of adjustment. The cap has a transverse partition with its bore formed with a screwdriver slot aligned with an enlarged similar slot in the top of the clip. Thus the fastener may be turned to a position where the projection of the top of the clip engages under the flange of the chassis.
