ASTM A Scope – This specification covers bolts, threaded rod, and anchors in diameters ranging from 1/4″ through 3″ (inclusive). It is a medium strength bolt . ASTM A is a material regulation covering hex headed bolts, rods, and anchor bolts. They are typically general use fasteners used in standard engineering. ASTM A is virtually identical in chemistry and strength to ASTM A and SAE J grade 5, but covers a larger diameter range and is not restricted by.
