Abstract: An appliance cabinet side wall is secured to a front frame member by a first mechanical fastening element of a fastening system. Subsequently, a trim piece is attached along the side wall through the use of a second mechanical fastening element which is threadably connected to the first fastening element. Most preferably, a blind-type rivnut is utilized to prevent any foam, used in insulating the cabinet, from leaking. Utilizing multi-functioning mechanical fastening elements minimizes the number of assembly components, eases assembly and enables the trim piece to be easily removed and/or replaced in case of damage, or even if the consumer desires to simply utilize a trim piece of another color or design.
