This section specifies general requirements for threaded fastening systems.
Within each requirement section, there are three sections of text. The actual requirement is shown in normal, non-italicized text along with a requirement label. Rationale for the requirement is shown as italicized text in brackets and is not to be considered a requirement. Additional guidance for each requirement is provided below the rationale statement as italicized text. The guidance is likewise not considered to be a requirement and is not an endorsement of a particular process or equation. The intent of the guidance is to provide additional clarifying language, a demonstration of a principle using a simple condition, or possible techniques or processes to show compliance with the requirement.
