Low Temperature Bolting

ASTM A320 Grade L7 Alloy Steel Heavy Hex Bolts
ASTM A320 Grade L7 alloy steel heavy hex bolts are impact-tested, quenched-and-tempered fasteners for low-temperature pressure vessels, valves, flanges, fittings and industrial equipment.
ASTM A320 Grade L7M Alloy Steel Heavy Hex Bolts
ASTM A320 Grade L7M alloy steel heavy hex bolts combine low-temperature impact requirements with restricted hardness for pressure-equipment joints where the project specifies L7M.
ASTM A320 L43 Low Temperature Stud Bolts
ASTM A320 Grade L43 high-strength low-temperature alloy-steel stud bolts, commonly based on AISI 4340 chemistry, with specified impact testing and documentation.
ASTM A320 L7 Low Temperature Stud Bolts
ASTM A320 Grade L7 alloy-steel stud bolts for low-temperature flange joints, supplied with specified impact testing, matching nuts and traceable documentation.
ASTM A320 L7M Low Temperature Stud Bolts
ASTM A320 Grade L7M low-temperature, controlled-hardness alloy-steel stud bolts with matching heavy hex nuts, impact testing and traceable documentation.
