Description

1/2" x 1-3/4" Conquest A325 Type 1 Fully Coarse Threaded Heavy Hex Structural Bolt

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 precision-engineered for high-load structural connections in steel frameworks. These bolts are manufactured to ASTM F3125 (A325) specifications and feature a plain finish for use in indoor or controlled environments where corrosion protection is not a primary concern.

Designed for Steel-to-Steel Connection Strength

With a fully coarse threaded shank and a heavy hex head, these bolts deliver maximum clamping force and load-bearing performance. They're ideal for steel-to-steel assemblies in bridges, buildings, and heavy infrastructure applications, offering unmatched durability and strength where it matters most.

Key Features

  • ASTM F3125 / A325 Type 1 Certified: Compliant with structural bolting standards for high-strength steel assemblies.
  • Fully Threaded Shank: Enables complete thread engagement for through-bolting and layered steel assemblies.
  • Plain Finish: Suitable for interior applications or projects with external corrosion control methods.
  • Heavy Hex Head: Provides superior torque handling and surface load distribution.
  • Carbon Steel Construction: Delivers dependable structural strength and integrity.
  • Application Use: Trusted in bridge construction, structural steel frameworks, and steel-to-steel fastening systems.

Common Applications

  • Structural steel framing in highway bridges and overpasses
  • Beam-to-column connections in industrial and commercial buildings
  • Assembly of large steel trusses and girders
  • Fastening steel members in infrastructure and heavy construction
  • Steel fabrication requiring high-strength, corrosion-resistant bolting

Installation Tips

  • Pair with galvanized nuts and hardened washers of matching finish to ensure corrosion resistance and fit
  • Torque to spec using approved installation methods such as turn-of-nut or calibrated wrench techniques
  • Inspect all mating surfaces and threads for cleanliness before installation to ensure full engagement and structural integrity
