Insert - Screw Thread, Thin Wall, Self-Locking UNS N07718, Silver Plated, Class: 185 Ksi/1025°F, Procurement Specification
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 Number System as UNS N07718.<p>Classification: tensile strength at room temperature 185 ksi minimum test temperature of parts 1025 degrees F.<p>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.<p>Primarily for use in aircraft engines application up to approximately 1025 degrees F where an insert with a self-locking feature is required at elevated temperature, having excellent tensile strength and resistant to relaxation.
Revise 3-cycle and 15-cycle Unloaded Self-Locking Torque tests to remove seating torque requirements.
