Joint between gas turbine engine components with bonded fastener(s)
An assembly is provided for a gas turbine engine. This gas turbine engine assembly includes a seal carrier, a seal land, a seal ring, a plate and a fastener. The seal carrier has an annular groove and extends between a first side and a second side. The seal land is opposite the annular groove. The seal ring seals a gap between the seal carrier and the seal land. The seal ring is seated in the annular groove. The plate is at the second side of the seal carrier. The fastener includes a head and an elongated member connected to the head. The head is at the first side of the seal carrier. The elongated member projects out from the head through the seal carrier, the seal ring and the plate. The elongated member is bonded to the plate.
