适用范围: Purpose??This SAE Parts Standard provides dimensional and quality assurance requirements for M6 through M36 metric sizes of studs in the following configurations in materials needed for ship system applications: a. Continuous thread studs in M thread profile. b. Double end studs??clamping type (also called bolt-studs) where both ends are of the same thread series but different lengths (M thread profile). A complete inch companion to this document is provided in SAE J2271. Field of Application??These studs are primarily for use in ship systems and equipment. The continuous thread studs and the constant strength double end studs are configurations particularly suited to applications which are subject to high shock requirements. Configurations and Part Identification Numbers??Figure 1 identifies the type and body configurations of the studs covered by the standard. The part numbering system provides a unique identification number for each stud configuration. The part identification number identifies thread type@ diameter@ type of stud and body diameter@ length of the stud@ and material including coating@ where applicable.
