Ship Systems and Equipment--Part Standard for Studs--Continuous and Double End (Inch Series) J2271_200901

This SAE Parts Standard provides dimensional and quality assurance requirements for studs in the following configurations in standard materials used for ship system applications: a. Continuous thread studs in UNRC and 8UNR series in the following threads and diameters: - UNRC threads (0.190 through 4 inches) - UNRF threads (0.190 through 1-1/2 inches) - 8UNR threads (1-1/8 through 4 inches) b. Double end studs (clamping type) where both ends are of the same thread length in the following threads and diameters: - UNRC threads (1/4 through 4 inches) - UNRF threads (1/4 through 1-1/2 inches) - 8UNR threads (1-1/8 through 4 inches) c. Double end studs (tap end type) where the tap end thread length is equivalent to 1-1/2 nominal diameters: - NC-5 interference-fit tap end thread with UNRC, UNRF or 8UN nut end threads (1/4 through 1-1/2 inches) - UNRC and 8 UN threads both ends (1/4 through 4 inches) - UNRC threads both ends (1/4 through 1-1/2 inches) A complete metric companion to this document is provided in SAE J2271M, therefore no metric equivalents are presented. These studs are primarily or 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.
