Scope:

This procurement specification covers bolts and screws made from a corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07001. The following specification designations and their properties are covered: AS7471 165 ksi minimum ultimate tensile strength at room temperature; 75 ksi stress-rupture strength at 1350 °F; and AS7471-1 165 ksi minimum ultimate tensile strength at room temperature; 99 ksi 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 temperatures up to approximately 1500 °F is required.

Rationale:

Correct error for stress–rupture test load in Table 2A (.3125-24 reduced pd), correct error in Table 3B for stress-rupture test sample size, clarify requirements for cold working the under head filet radius, and general editorial update.
