Adjacent tabs are disposed in their associated crowns at an outer wall thereof facing one another to permit the facing tabs to be soldered together to fix the adjacent crowns relative to each other. Each of the tabs is provided with threaded openings extending through each tab for receiving a threaded member to position the tab during investment molding of the crown and for receiving solder when the facing tabs are secured together.
