1-1/4" x 9-1/2" 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 1-1/4" Conquest A325 Type 1 Heavy Hex Structural Bolt is engineered to meet the demands of structural steel connections in bridges, buildings, and other high-load environments. Compliant with ASTM F3125 standards, this bolt delivers the strength and reliability required for steel-to-steel fastening.

Built for Critical Structural Connections

Featuring a coarse 7 threads per inch profile and heavy hex head, this bolt is optimized for torque-heavy installations. The hot dip galvanized finish provides superior corrosion protection, ensuring long-term performance in outdoor and high-moisture environments.

Key Features

• 1-1/4" Diameter Heavy Hex Bolt: Engineered for structural steel connections requiring maximum strength.
• 7 TPI Coarse Thread: Provides high load-bearing capacity and resists vibration-induced loosening.
• ASTM F3125 / A325 Type 1 Compliant: Meets industry standards for structural integrity and reliability.
• Hot Dip Galvanized: Corrosion-resistant finish for use in bridges, highways, and exterior steel frameworks.
• Heavy Hex Head: Allows for high-torque tightening and distributes stress evenly.
• Ideal for Steel-to-Steel Fastening: Common in bridge construction, building frameworks, and heavy-duty fabrication.

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
