AN, MS, NAS
"MS" and "NAS" are commonly used prefixes that refer to specific standards within the aerospace industry:
-
MS: MS stands for "Military Standard." These standards were established by the United States Department of Defense (DoD) to define various specifications for materials, equipment, processes, and components used in military applications.
-
NAS: NAS stands for "National Aerospace Standard." These standards are used in the aerospace industry to establish consistent design, manufacturing, and testing requirements for aerospace components and equipment.
"MS" or "NAS" nuts refers to nuts that adhere to the specifications set forth by either the Military Standard (MS) or the National Aerospace Standard (NAS) for use in aerospace or military applications. These nuts would be manufactured and tested to meet the specific requirements outlined in these standards to ensure their suitability for demanding environments and critical applications.
It's important to note that the specific details and requirements of MS and NAS standards can vary widely depending on the specific part, application, and revision of the standard in question. If you need nuts that adhere to MS or NAS standards, it's recommended to consult the relevant standards documents or work with suppliers who specialize in aerospace and military components to ensure you are using the appropriate fasteners for your specific needs.
