This SAE Standard covers the mechanical and material requirements for inch-series steel bolts, screws, studs, screws for sems¹, and U-bolts² in sizes to 1-1/2 in. inclusive.

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.

The mechanical properties included in Table 1 were compiled at an ambient temperature of approximately 20 °C (68 °F). These properties are valid within a temperature range which depends upon the material grade used and thermal and mechanical processing. Other properties such as fatigue behavior, corrosion resistance, impact properties, etc., are beyond the scope of this document and responsibility for ensuring the acceptability of the product for applications where conditions warrant consideration of these other properties shall be borne by the end user.

This standard defines the common nonconformity data definition and documentation that shall be exchanged between an internal/external supplier or sub-tier supplier, and the customer when informing about a nonconformity requiring formal decision. The requirements are applicable, partly or totally, when reporting a product nonconformity to the owner or operator, as user of the end item (e.g., engine, aircraft, spacecraft, helicopter), if specified by contract.

Reporting of nonconformity data, either electronically or conventionally on paper, is subject to the terms and conditions of the contract. This also includes, where applicable, data access under export control regulations.

This practice provides recommendations concerning the chemical milling of aluminum, magnesium, high temperature nickel alloys, titanium alloys, copper alloys, and specialty alloys.

This specification establishes the requirements for the production of reliable, repeatable, reproducible aerospace parts by fused filament fabrication but is not limited to such application. This specification establishes the requirements to approve new machines, processes, and materials. Specifically, this specification covers machine configuration, operating software, machine calibration, machine and build parameters, and testing methodology required to create aerospace parts. This specification also defines the user’s responsibility for following the specified requirements.

This specification covers an aluminum alloy in the form of pre-alloyed powder.

This specification covers a corrosion and heat-resistant steel alloy in the form of pre-alloyed powder.

This specification establishes process controls for the repeatable production of aerospace parts by EB-DED-Wire. It is intended to be used for metal aerospace parts produced by additive manufacturing (AM), but usage is not limited to such applications.

This specification covers a titanium alloy in the form of pre-alloyed powder.

This specification covers particle size classifications and corresponding particle size distribution requirements for metal powder feedstock conforming to a classification.

This specification covers a heat-resistant gamma titanium aluminide alloy in the form of pre-alloyed powder.
