1" x 4-3/4" 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.

Conquest 1" A325 Type 1 Heavy Hex Structural Bolts are engineered for strength, durability, and corrosion resistance in critical structural steel applications. Manufactured to meet ASTM F3125 (A325) standards and finished with hot dip galvanization, these bolts are built to provide reliable performance in outdoor and industrial environments.

Heavy‑Duty Bolting for Steel Framing and Infrastructure

Designed for steel‑to‑steel connections, these bolts combine a heavy hex head with coarse 8 threads per inch to ensure secure engagement and maximum clamping force. The hot dip galvanized finish protects against rust and weathering, making them ideal for highway construction, bridge assemblies, commercial steel framing, and other high‑load structural jobs.

Key Features

• 1" Diameter Carbon Steel: Delivers the strength required for demanding structural connections.
• Coarse 8 TPI Threads: Provides secure, vibration‑resistant engagement in load‑bearing applications.
• ASTM F3125 / A325 Type 1 Certified: Meets strict industry standards for structural bolting performance.
• Hot Dip Galvanized Finish: Ensures corrosion resistance for outdoor and exposed environments.
• Heavy Hex Head Design: Increases torque capacity and load distribution for high‑strength joints.
• Steel‑to‑Steel Fastening: Ideal for bridges, buildings, structural frames, and industrial infrastructure.
• Contractor Preferred: Trusted by pros for critical bolting in tough environments.

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
