These standards from ISO and SAE cover screw requirements. This list covers rolling screw thread inserts standards.

SAE AS 1229D-2018

Insert, Screw Thread, Helical Coil, Stud Locking, Performance Standard For

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.

SAE AS 1349B-2018

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

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.

SAE AS 3506B-2014 (SAE AS3506B-2014)

Insert - Screw Thread, Thin Wall, Self-Locking, UNS N07718, Silver Plated, Class: 185 ksi/1025 ┬░F, Procurement Specification

This SAE Aerospace Standard (AS) establishes the requirements for AS3504 and AS3505 thin wall self-locking inserts made from a corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07718.

SAE AS 4892B-2019

Insert, Screw Thread, Self-Locking, UNS S66286, Locked in, Key Locked, Procurement Specification for

This procurement specification covers inserts made from A286 alloy of the type identified under the Unified Numbering System as UNS S66286 which have self-locking internal threads and integrated locking keys to positively secure the insert against rotation when properly installed in threaded holes.

SAE AS 4976A-2019

Insert, Screw Thread, Non-Locking, UNS S66286, Locked in, Key Locked, Procurement Specification for

This procurement specification covers inserts made from A286 alloy of the type identified under the Unified Numbering System as UNS S66286 which have non-locking internal threads and integrated locking keys to positively secure the insert against rotation when properly installed in threaded holes.

SAE AS 7245B-2019

Inserts, Screw Thread, Helical Coil, 19Cr-9.2Ni, Corrosion Resistant Steel, Procurement Specification for

This specification covers closely-wound helical coil, screw thread inserts made of a corrosion resistant steel formed wire with a chemical composition in accordance with Table 1 and identified under the Unified Numbering System as UNS S30200 or UNS S30400 that can be formed by an insert manufacturer to achieve the requirements of this procurement specification. The inner surface of the insert coil, after assembly into a screw thread tapped hole, provides internal threads of standard 60° Unified form.

SAE AS 7246-1993 (SAE AS7246-1993)

Inserts, Screw Thread, Helical Coil 72Ni 15.5Cr 0.95(Cb+Ta) 2.5Ti 0.70Al 7.0Fe Corrosion and Heat Resistant Alloy Procurement Specification for ( Reaffirmed: Apr 1999 Jul 2004 )

This specification covers closely-wound helical coil, screw thread inserts made from an age hardenable nickel base alloy formed wire of the type identified under the unified number system as UNS N07750. The inner surface of the insert coil, after assembly into a screw thread tapped hole, provides internal threads of standard 60 degrees unified form.

SAE MA 1565C-2014 (SAE MA1565C-2014)

Inserts, Screw Thread, Helical Coil Metric Series, Procurement Specification For (Stabilized: Dec 2014)

This SAE Metric Aerospace Standard defines the requirements for corrosion resistant steel helical coil metric series screw thread inserts made from formed wire, the inner surfaces of which, after assembly, provide internal threads of the diameter and pitch specified on the drawing.

SAE MA 1567C-2019

Insert, Screw Thread, Helical Coil Metric Series, Standard Assembly Dimensions for

This SAE Metric Aerospace Standard (MA) provides for helical coil screw thread inserts, both free running and self-locking, installation screw thread dimensional data and guidance on insert length selection. The document also provides formulas for determining requirements when non standard insert lengths are necessary.
