7/8" x 2-1/2" Conquest A325 Type 1 Heavy Hex Structural Bolt with Hot Dip Galvanized 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.

The 7/8" Conquest A325 Type 1 Heavy Hex Structural Bolt is designed for demanding structural applications requiring high-strength steel-to-steel connections. Manufactured to ASTM F3125 / A325 Type 1 standards, this bolt delivers dependable performance in bridgework, building frameworks, and infrastructure construction.

7/8" Hex Bolt for Reliable in High-Stress Environments

With 9 threads per inch and a coarse thread profile, this bolt ensures a secure fit under heavy loads and resists loosening due to vibration. The hot dip galvanized coating offers superior protection against corrosion in outdoor or exposed settings, making it ideal for harsh environments.
