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.
