This procurement specification covers bolts, screws and studs made from a work-strengthened corrosion and heat resistant, age Hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07718. The following properties are covered:
220 ksi minimum ultimate tensile strength at room temperature
180 ksi minimum ultimate tensile strength at 900 °F
114 ksi tension to 11.4 ksi tension fatigue at room temperature
Provide industry with a 220 ksi procurement specification for bolts, screws and studs.

E-25 General Standards for Aerospace and Propulsion Systems
The SAE E-25 General Standards for Aerospace & Propulsion Systems committee addresses aerospace propulsion systems and components. These systems and components include bolts, screws, nuts, washers, studs, rivets, pins, covers, O-rings, brackets, plugs and associated procurement requirements, as well as solid film lubricants and design specifications for screw threads and fastener assembly requirements.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
