Scope:

This specification covers bolts and screws made from a corrosion and heat resistant age hardenable iron base alloy of the type identified under the Unified Numbering System as UNS S66286, and of 130 000 psi tensile strength at room temperature, with maximum test temperature of parts at 1200 °F.

Primarily for aerospace propulsion system applications where a good combination of strength and resistance to relaxation at elevated temperatures is required.

Rationale:

Bring AS7479 para 3.3.1 Blanks: heading temperature "not higher than 1600 °F" into agreement with AS7477, AS7478 and AS7481 para 3.3.1 Blanks: heading temperature "not higher than 2100 °F" and update document to current SAE format requirements.
