5/8" x 2-1/4" 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 5/8" Conquest A325 Type 1 Heavy Hex Structural Bolt is engineered for high-strength steel-to-steel fastening in structural applications. Manufactured to ASTM F3125 / A325 Type 1 specifications, this bolt delivers reliable performance in critical infrastructure and construction settings.

Built for Structural Strength

Featuring 11 threads per inch and a coarse thread profile, this bolt provides strong clamping force and dependable vibration resistance. The heavy hex head design ensures maximum torque and load distribution, while the hot dip galvanized finish protects against corrosion in outdoor and high-moisture environments.

Key Features

  • 5/8" Diameter Heavy Hex Bolt: Designed for structural bolting in steel construction.
  • 11 TPI Coarse Threads: For secure installation and vibration resistance.
  • ASTM F3125 / A325 Type 1 Compliant: Certified for use in bridges, highways, and structural steel projects.
  • Hot Dip Galvanized Coating: Ensures long-term corrosion resistance and outdoor durability.
  • Heavy Hex Head: Allows higher torque application for secure fastening.
  • Common Uses: Ideal for structural steel connections, infrastructure, heavy fabrication, and construction.

Common Applications

  • Structural bolting in bridges and highway infrastructure
  • Steel-to-steel connections in commercial and industrial buildings
  • Pre-engineered metal building assembly
  • High-load steel frameworks in outdoor environments
  • Corrosion-prone structural installations requiring high-strength fasteners

Installation Tips

  • Use only with galvanized nuts and hardened washers to ensure corrosion resistance and proper load transfer
  • Follow specified torque methods such as turn-of-nut or calibrated wrench to meet preload requirements
  • Inspect bolt threads and mating components for cleanliness and damage before installation
