Scope
This specification establishes the requirements for the following types of self locking nuts:
-
a
Wrenching nuts: i.e., hex, double hex, spline drive.
-
b
Anchor nuts: i.e., plate nuts, gang channel nuts, shank (clinch) nuts.
The wrenching nuts, shank nuts, and nut elements of plate and gang channel nuts are made of corrosion and heat resistant steel of the type identified under the Unified Numbering System as UNS S66286.
Rationale
This document has been determined to contain basic and stable technology which is not dynamic in nature.

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.
Reference
* 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.
