This specification covers metric bolts and screws made from a corrosion and heat resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS NO7001. The following specification designations and their properties are covered: MA3378 1210 MPa minimum ultimate tensile strength at room temperature 520 MPa stress-rupture strength at 730 °C MA3378-1 1210 MPa minimum ultimate tensile strength at room temperature 726 MPa minimum ultimate shear strength at room temperature. Primarily for aerospace propulsion system applications where a good combination of tensile strength and resistance to relaxation at elevated temperature up to approximately 815 °C is required.
