A mount for an annular burner for a gas turbine engine includes a pin attached to the engine case fitting through a hole in the lug extending from the burner, a bushing frictionally fitted to the pin with a flange bearing against the surface of the lug and a washer overlying the flange and bearing against the opposite surface of the lug. The washer and lug are fabricated from a nickel base alloy and the bushing is fabricated from a cobalt base alloy. The bushing is undercut adjacent the washer to reduce the wall thickness and allow for thermal expansion when the washer is tack welded to the lug.
