Hex Bolts, A307 Grade A (inch)
Click image to enlarge
The ASTM A307 bolts are available in Grade A which are manufactured from low-carbon steel, thus yielding a lower strength. These bolts are best suited for low-stress applications in general construction projects. They are available in plain steel, zinc, zinc-yellow, and hot dipped galvanized for options to best fit the project needs. To complete an installation, consider if you need any hex nuts to fully secure the connection.
