US Patent 7128512 Panel fastener system

A fastener system for mounting to a panel includes a twist-in fastener that rotatably engages an opening in the panel. The fastener includes a fastener body defining an opening extending through the fastener body for receiving a mating fastener, a plurality of facets positioned around the fastener body opening for facilitating the mounting of the fastener onto the panel, and a fastener base. Panel-engaging members extend outwardly from the fastener base to rotatably mount the fastener through the panel opening and onto the panel. At least one anti-rotation member also extends outwardly from the fastener base to prevent the mounted fastener from backing out of the panel opening upon the removal of the mating fastener.
