Scope
This SAE Aerospace Standard (AS) covers helical coil locking screw thread inserts made from formed wire in which the inner surface of the coil, after assembly, provides threads of standard Unified 60° form as specified on the assembly drawing. This document also covers the performance requirements of the locking feature of the insert which will retain Unified ANSI B1.1 (UN Profile) or AS8879 (UNJ Profile) external threaded parts.
Rationale
AS1349A has been reaffirmed to comply with the SAE five-year review policy.

* 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.
