Specifies requirements for fasteners mainly intended for bolting for flanges and other pressure-containing purposes. Covers a metric series for the temperature range -50¿¿C to +300¿¿C and an inch series for -250¿¿C to +575¿¿C. Appendices deal with strength and performance of inch series studbolts at elevated temperatures, method for checking squareness of thread, sampling for mechanical properties, material standards for inch bolting and metric equivalents for inch series studbolts and nuts.
