5/16″ x 2″ Conquest A307 Grade A Hex Bolt with Plain Finish

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 5/16″ diameter Conquest A307 Grade A Hex Bolts are designed for general-purpose fastening in dry, non-corrosive environments. With coarse threads at 18 TPI, a hex head design, and a plain finish, they provide consistent strength and ease of installation for indoor structural work and maintenance tasks.
