Description

1-1/8" x 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 1-1/8" A325 Type 1 Heavy Hex Structural Bolts are built for high-strength steel-to-steel fastening in structural and infrastructure applications. Manufactured from carbon steel and coated with a hot dip galvanized finish, these bolts are designed for long-lasting performance in demanding outdoor environments.

Engineered for Structural Steel Connections

These structural bolts meet ASTM F3125 (A325 Type 1) standards, ensuring exceptional tensile strength and reliability. The coarse 8 threads per inch and heavy hex head provide secure torque transfer, making them ideal for highway, bridge, and commercial construction where critical joint integrity is required.

Key Features

  • 1-1/8" Diameter Carbon Steel: High-load capacity for steel-to-steel connections in large structures.
  • Coarse 8 TPI Threads: Provides robust engagement in structural assemblies and resists vibration loosening.
  • ASTM F3125 / A325 Type 1: Certified for structural bolting in compliance with federal and industry standards.
  • Hot Dip Galvanized Coating: Superior corrosion resistance for outdoor and exposed use.
  • Heavy Hex Head: Distributes load evenly and enables higher torque application.
  • Ideal for Bridges & Infrastructure: Trusted for high-strength steel framing in transportation and industrial builds.
  • Pro-Grade Construction Fastener: Dependable performance for contractors and steel fabricators.

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
