ASME B18.2.1 Grade 5 Bolts

ASME B18.2.1 Grade 5 bolts are high-strength medium carbon steel fasteners, heat-treated for superior mechanical properties, and conform to the ASME B18.2.1 standard. These bolts are commonly used in machinery, automotive, construction, and industrial applications where medium to high-strength connections are required. The surface can be zinc-plated or phosphated for enhanced corrosion resistance and extended service life.
