(R) Insert - Screw Thread, Thin Wall, Self-Locking, UNS N07718, Silver Plated, Class: 185 ksi/1025 °F, Procurement Specification
|Publication Date:||1 February 2014|
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.
Tensile strength at room temperature 185 ksi minimum. Maximum test temperature of parts is 1025 °F.
The method of locking the insert into parent material to resist rotation to be by means of swaging the insert knurled collar into a hole prepared in per AS3508.
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.
