Grades - ASTM A320

ASTM A320 Grade L7M bolts and threaded studs are also manufactured from quenched and tempered alloy steel. The mechanical properties and requirements are lower compared to L7 bolts. L7M bolts are required to have 100% hardness testing. The final heat-treatment must be performed after machining or rolling of the threads and any type of cutting.
