5/8″ x 22″ Conquest A307 Grade A Hex Bolt – Plain

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 5/8″ diameter Conquest A307 Grade A Hex Bolts are built from carbon steel with coarse 11 TPI threading for dependable grip in light to moderate strength applications. The plain finish makes them ideal for interior construction, equipment installation, and non-corrosive maintenance tasks.
