A320 L7 All Thread Rod

ASTM A320 Grade L7 all thread rod is manufactured from alloy steel, quenched and tempered. Dimensional specifications are governed by ASME B18.31.3. Inch series fasteners meeting ASTM A320 Grade L7 specifications are typically used to secure valves, flanges and fittings in low temperature applications. A320 L7 all thread rod having diameters above 1" are most common 8UN (8 threads per inch).
