適用范圍：This procurement specification covers aircraft quality metric spanner nuts for retaining shaft mounted parts. Nuts are made from a corrosion and heat resistant age hardenable iron base alloy of the type identified under the Unified Numbering System at UNS S66286, and silver plated. Thread shear proof strength at room temperature is 450 MPa. Primarily for aerospace propulsion system applications to retain parts on shafts where a good resistance to relaxation is required.
