A heat shield and gasket assembly has three members including a first heat shield, a second heat shield, and a gasket. Each of the members has a flange portion and the flange portion of the gasket is sandwiched is between the flanges of the two heat shields. The flange portion of the gasket is thinner than the flange portions of the heat shields. The thinness of the gasket flange permits it to engage threaded assembly fasteners without compromising the thread integrity of the fasteners.

A nut is comprised of a one piece stamping having a base wall with an integrally formed conical nut. A frame member has a bolt receiving first aperture in a first planar wall and a nut receiving second aperture in a second planar wall extending at a generally perpendicular angle with respect to the first planar wall. The stamping has integral stop tabs which engage with the frame member to limit the insertion of the stamping into the second aperture so that the conical nut is registered with the bolt receiving first aperture. First and second integral flexure arms flex inwardly upon insertion of the stamping through the second aperture and then engage with the inner surface of the frame member to retain the stamping against removal from the frame member. Integral flanges engage with the walls of the frame member defining the second aperture to cooperate with the stop tabs and the flexure arms to maintain the base wall in position registering the conical nut with the bolt receiving first aperture and to restrain the stamping against rotation relative to the frame member upon the threaded installation of a bolt into the conical nut.
