- Aerospace Standard
- MA1573A
- Reaffirmed
Downloadable datasets available
Annotation ability available
Sector:
Issuing Committee:
Language:
English
Scope
This specification establishes the requirements for the following types of self-locking nuts:
-
a
Wrenching nuts: that is, hex, double hex, spline drive
-
b
Anchor nuts: that is, plate nuts, gang channel nuts, shank nuts
The wrenching nuts and shank nuts are made of low alloy steels, and the nut elements of plate and gang channel nuts are made of carbon steels or low alloy steels and having MJ threads to ISO 5855/2. Nuts have 1100 MPa tensile strength class at room temperature. Maximum test temperature of parts at 235 °C.
Rationale
MA1573A has been reaffirmed to comply with the SAE five-year review policy.

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.
