Specifies requirements for fasteners mainly intended for bolting for flanges and other pressure-containing purposes. Covers a metric series for the temperature range -50 degrees Celsius to +300 degrees Celsius and an inch series for -250 degrees Celsius to +575 degrees Celsius. 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.
