適用范圍：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 minimum 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); Different thread forms on each end are permissible. c. Double end studs (tap end type) where the tap end thread length is equivalent to 1-1/2 nominal diameters: Tap End Thread Forms and Diameters Nut End Thread Forms and Diameters; NC-5 interference-fit tap end threads (1/4 through 1-1/2 inches); UNRC threads (1/4 through 4 inches) - UNRC threads (1/4 through 4 inches); UNRF threads (1/4 through 1-1/2 inches); UNRF threads (1/4 through 1-1/2 inches); 8UNR threads (1-1/8 through 4 inches); 8UNR threads (1-1/8 through 4 Inches) These studs are primarily for use in ship systems and equipment. The continuous thread studs and the reduced body diameter double end studs are configurations particularly suited to applications that are subject to high impact (H.I.) shock requirements.
