Steel Alloys

Fastener standards for materials address the very metals that fasteners are composed of. With different applications requiring varying levels of corrosion resistance, resistance to deformity and high strength at different high temperatures, different manufacturing processes, dimensions, as well as considerations of matching metals to prevent galvanic corrosion. This list addresses those made from steel alloys.

SAE AS 269J-2018

Identification of Material for AN, MS, and AS Engine and Propeller Standard Utility Parts and Also for Company Parts

This SAE Aerospace Standard (AS) provides material identification codes for aluminum alloys, copper alloys, carbon steels, alloy steels, titanium alloys, corrosion resistant materials, and heat resistant materials that are used to make AN, MS, and AS engine and propeller standard utility parts. This document also provides similar material codes for company parts (such as nuts, bolts, etc.) having design configuration similar to other company parts or the engine and propeller standard utility parts (AN, MS, and AS) that are not of the same material.

SAE J 1199-2013 (SAE J1199-2013)

Mechanical and Material Requirements for Metric Externally Threaded Steel Fasteners ( Stabilized: Feb 2013 )

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. This SAE Standard covers the mechanical and material requirements for eight property classes of steel, externally threaded metric fasteners in sizes M1.6 through M36, inclusive, and suitable for use in automotive and related applications. Products included are bolts, screws, studs, U-bolts, preassembled screw and washer assemblies (sems), and products manufacturered the same as sems except without washer. Products not covered are tapping screws, thread-rolling screws, and self- drilling screws. Mechanical and material requirements for these products are covered in other SAE documents. The term stud as referred to herein, applies to a cylindrical rod of moderate length, threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts. For specification purposes, this document treats U-bolts as studs. Thus, wherever the world studs appears, U-bolts is also implied. U-bolts covered by this document are those used primarily in the suspension and related areas of vehicles. (Designers should recognize that the U configuration may not sustant a load equivalent to two bolts or studs of the same size and grade; thus actual load-carrying capacity of U-bolts should be determined by saddle load tests.)
