An apparatus includes a chevron ring, a first seal and a plurality of fasteners. The chevron ring extends axially along an axis to and forms a downstream trailing edge of an exhaust nozzle. The chevron ring includes a ring base and a plurality of chevrons. The ring base includes a plurality of blind apertures. Each blind aperture projects radially inward towards the axis partially into the ring base. The fire seal is disposed radially outboard of the chevron ring. The fire seal axially and circumferentially overlaps the ring base. The fasteners mount the fire seal to the chevron ring. Each fastener includes a shank and a head. The shank projects longitudinally out from the head, through the fire seal, and is threaded into a respective one of the blind apertures. The fire seal is radially clamped between the head of each of the fasteners and the ring base.
