Heavy-Duty Hex Bolts

Click image to enlarge
If you need a standard hex bolt for your project, explore our ASTM A307 hex bolts available in Grade A and Grade B. Our A307 Grade A hex bolts are ideal for light-duty applications where component separation is preferred over structural damage in the event of a bolt failure. These fasteners offer a minimum tensile strength of 60,000 PSI and usually feature a '307A' head marking.

For projects demanding a stronger bolt, consider our A307 Heavy Hex Bolts, Grade B. Manufactured from heavier carbon steel, these hex head bolts are suitable for applications requiring higher strength, with a minimum tensile strength ranging from 60,000 to 100,000 PSI. All our ASTM A307 hex bolts come in plain finish, zinc-plated, and hot-dipped galvanized options to meet diverse project needs and offer corrosion resistance.

Finally, for your most heavy-duty requirements, we offer B7 Heavy Hex Bolts, providing an impressive minimum strength of 125,000 PSI. These robust hex bolts are typically in stock in plain steel only, but we can arrange secondary processing for custom plating if needed.
