ABSTRACT:
An insulated blind rivet mounting arrangement in an aperture in a wall including a blind rivet having a tubular rivet member and a actuating rod that is disposed within the tubular member and is adapted for axial withdrawal therefrom; an insulating sheath made of non-electrically conductive material positioned over said tubular rivet member; and said blind rivet actuating rod being removable from said tubular rivet member for expanding the tubular rivet member and insulating sheath into tight interfitting relation with each other within the wall aperture. Alternative embodiments are disclosed in which one or more coaxially disposed tubular flanged members are utilized to complete the mounting, with the insulating sheath being effective to thermally and electrically insulate the tubular rivet member. The insulating sheath, which preferably is made of a resilient plastic material, also is effective for creating a substantially vibration-free mounting within the wall aperture.
