Scope:

This SAE Aerospace Standard (AS) covers helical coil stud 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 standard 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.

To establish the performance requirements of helical coil stud locking screw thread inserts.

Rationale:

Update specification to add current CADMIUM plate usage WARNING note to 4.1 and removed from 5.; replace MIL-S-8879 with AS8879 and MS33537 with NASM33537 throughout specification; added paragraphs 2.1.5, 7 and 7.1.
