ASTM A307 Grade A Hex Bolts

The ASTM A307 Hex Bolt is a specification for general-purpose fasteners made from low-carbon steel. These bolts are most commonly supplied as Grade A, which covers bolts, studs, and threaded rods with a tensile strength requirement ranging from 60 ksi to 100 ksi. These Hex Head Bolts are primarily used for general, non-critical commercial and structural applications where moderate strength is sufficient, such as connecting non-pressure parts, light structural assemblies, and in general machinery. Due to their cost-effectiveness and versatility, they are one of the most widely used industrial fasteners globally. Zeron Fasteners manufactures and supplies a comprehensive range of A307 Hex Bolts, often provided with a zinc-plated or hot-dip galvanized finish for enhanced corrosion resistance.
