A fan assembly has a fan housing defining mounting apertures, a sheet metal mounting member for mounting the fan housing thereon, mounting tabs extending outwardly of the mounting member and received within the mounting apertures of the fan housing, and threaded fasteners received within the mounting apertures of the fan housing and engaging both the mounting tabs and the fan housing to secure the fan housing to the mounting member. Each mounting tab is formed by piercing the sheet metal mounting member with a forming tool, and moving the forming tool through the pierced mounting member to thereby move the pierced metal in the shape of the tab outwardly of the mounting member. The mounting tabs are received within the mounting apertures of the fan housing, and self-tapping fastener are inserted into the mounting apertures of the fan housing and engage both the fan housing and the mounting tabs to secure the fan housing to the mounting member.
