1/2" 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.

Conquest 1/2" A325 Type 1 Heavy Hex Structural Bolts are engineered for demanding structural steel applications where strength, compliance, and corrosion resistance are critical. Built from carbon steel and finished with hot dip galvanizing, these bolts deliver lasting performance in bridge, highway, and commercial steel frameworks.

Designed for Steel-to-Steel Structural Connections

These heavy hex bolts meet ASTM F3125 (A325 Type 1) specifications and are widely used in infrastructure and industrial steel assembly. The 13 threads per inch coarse thread and robust hex head ensure secure fastening under dynamic and static loads.

Key Features

• 1/2" Diameter Carbon Steel: Reliable for structural joints in steel frame assemblies.
• 13 TPI Coarse Threads: Ensures strong clamping force and resists loosening under vibration.
• ASTM F3125 / A325 Type 1 Compliant: Rated for structural applications in bridge, highway, and commercial builds.
• Hot Dip Galvanized Finish: Long-term protection against rust in exposed environments.
• Heavy Hex Head Design: Distributes pressure evenly and enables high-torque installation.
• Ideal for Infrastructure Projects: Trusted by pros for fastening structural steel beams and components.
• Compatible with A325 Hex Nuts: Use with matching hardware for code-compliant assemblies.

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
