Description

5/8" x 3-3/4" Conquest A325 Type 1 Heavy Hex Structural Bolt Plain 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 Heavy Hex Structural Bolts in 5/8" diameter are built for critical structural bolting where strength, durability, and reliability are non-negotiable. Manufactured to ASTM F3125 standards (incorporating A325), these bolts are widely used in steel-to-steel connections for bridgework, infrastructure, and commercial steel assemblies.

Trusted Heavy Duty Bolts for Infrastructure and High-Load Steel Framing

With a 1-1/4" thread length and coarse 11 TPI threading, these carbon steel bolts ensure solid engagement and consistent load distribution. The heavy hex head increases wrenching area for greater torque and holding power, making them a go-to for steel fabrication and structural projects requiring code-compliant performance.

Key Features

  • 5/8" Diameter Carbon Steel: Delivers high tensile strength for demanding structural assemblies.
  • 1-1/4" Thread Length (11 TPI): Provides reliable grip and controlled load transfer in joints.
  • ASTM F3125 / A325 Compliant: Meets modern engineering standards for structural steel bolting.
  • Coarse Thread Type: Ensures strong bite and efficient installation in high-load applications.
  • Heavy Hex Head Design: Increases torque capacity and load-bearing surface area.
  • Steel-to-Steel Focus: Ideal for bridges, beams, columns, and steel frameworks.
  • Infrastructure-Grade Performance: Used in commercial construction, highway systems, and heavy industrial builds.

Common Applications

  • Structural steel connections in bridges and highways
  • Steel frame assembly in commercial and industrial buildings
  • High-strength bolting for columns, girders, and braces
  • Steel-to-steel joints in large-scale infrastructure projects
  • Fabrication and erection of pre-engineered metal buildings

Installation Tips

  • Use with heavy hex nuts and hardened washers with the same finish/standards to ensure proper fit and load transfer
  • Follow approved tensioning methods such as calibrated wrench or turn-of-nut for proper preload
  • Verify bolt length allows for full thread engagement and minimum thread exposure as per project specs
