Product Code:SAE AS7455
Title:Bolts and Screws, Steel, Low Alloy, Heat Resistant Hardened and Tempered, Roll Threaded
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: This procurement specification covers aircraft quality bolts and screws made from a low alloy, heat resistant steel of the type identified under the Unified Numbering System as UNS K14675, and of a series of room temperature tensile strengths ranging from 140 000 psi to 195 000 psi. Primarily for aerospace propulsion system applications where high strength at temperatures up to approximately 900掳 F is required and the part is protected against corrosion.
