Any specification that is referenced in this Material Order Data sheet is required to be to the latest revision at time of award.
6.1 Intended use. Fasteners meeting this specification are intended for general, high temperature, high strength and corrosive environment applications where a high degree of reliability is required. It is designed to be used to acquire commercial off-the-shelf fasteners with added inspections to verify the high degree of reliability required. Fastener types and grades have been selected to meet diverse applications which include: elevated temperatures, immersion in sea water, salt air/marine environments, high preloads and high shock loadings.
