Insert, Screw Thread, Helical Coil, Locking (Low Friction Systems), Performance Standard For AS1349

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 degrees form as specified on the assembly drawing. This document also covers the performance requirements of the locking feature of the insert which will retain United ANSI B1.1 (UN Profile) or AS8879 (UNJ Profile) external threaded parts.

To establish the performance requirements of helical coil locking screw thread inserts for use in fastening systems utilizing a lubricant which induces a low coefficient of friction between insert and fastener.
