1.1 Scope:
This SAE Aerospace Standard (AS) establishes the requirements for AS3504 and AS3505
thin wall self-locking inserts made from a corrosion and heat resistant, age hardenable
nickel base alloy of the type identified under the Unified Numbering System as UNS
N07718.
1.1.1 Classification: Tensile strength at room temperature 185 ksi minimum. Maximum test
temperature of parts 1025 °F.
1.1.2 The method of locking the insert into parent material to resist rotation to be by means of
swaging the insert knurled collar into the prebroached knurl of the parent material.
1.2 Application:
Primarily for use in aircraft engines application up to approximately 1025 °F where an
insert with a self-locking feature is required at elevated temperature, having excellent
tensile strength and resistance to relaxation.strRefField
