At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A576. Standard specification for special-quality hot-wrought carbon steel bars (rounds, squares, hexagons, flats). A bar-stock feedstock spec controlled by chemistry (SAE grade); it does NOT specify mechanical properties for the finished bar – mechanicals depend on the grade and any subsequent heat treatment.
