Description

1-1/8" x 2-1/4" Conquest A325 Type 1 Fully Coarse Threaded Heavy Hex Structural Bolt with 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 A325 Type 1 Fully Coarse Threaded Heavy Hex Structural Bolts are engineered for high‑strength steel‑to‑steel connections in critical structural applications. Manufactured to meet ASTM F3125 (A325) specifications and finished with hot dip galvanization, these bolts combine tensile strength with long‑lasting corrosion resistance for demanding builds such as bridges, highways, and industrial steel frameworks.

A325 Hex Bolts for Structural Integrity and Corrosion Protection

Featuring a fully coarse threaded shank, these bolts provide maximum engagement throughout the bolt’s length, offering secure clamping in thick materials or layered steel assemblies. The hot dip galvanized coating enhances durability in outdoor and high‑moisture environments, while the heavy hex head supports greater torque and load distribution where strength matters most.

Key Features

  • ASTM F3125 / A325 Type 1 Certified: Meets structural bolting standards for high‑load steel connections.
  • Fully Coarse Threaded Shank: Provides deep engagement and secure clamping across various thicknesses.
  • Hot Dip Galvanized Finish: Offers robust corrosion resistance for outdoor and infrastructure use.
  • Heavy Hex Head Design: Allows for higher torque application and better load distribution.
  • Carbon Steel Construction: Engineered for strength and reliability in critical structural assemblies.
  • Steel‑to‑Steel Applications: Ideal for bridges, building frames, highway structures, and large steel builds.
  • Contractor‑Ready Performance: Trusted by professionals for consistent structural results.

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
