A490M is a metric high-strength heavy hex structural bolt specifically designed for use in heavy construction and industrial steel structures. Manufactured from quenched and tempered alloy steel, it features a tensile strength ranging from 1040 to 1210 MPa. Due to its extreme hardness, A490M bolts are strictly prohibited from being hot-dip galvanized to prevent hydrogen embrittlement. They are engineered to withstand significant shear and tensile loads, making them essential fasteners in bridge and skyscraper connections.
