3/8″ x 7-1/2″ Conquest A307 Grade A Hex Bolt – Hot Dip Galvanized

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

These 3/8″ diameter Conquest A307 Grade A Hex Bolts are built from carbon steel and hot dip galvanized to withstand harsh outdoor conditions. With coarse threads and a hex head design, theyre ideal for wood-to-wood or wood-to-steel fastening in residential, commercial, and agricultural construction.
