7/8″ x 7-1/2″ Conquest A325 Type 1 Heavy Hex Structural Boltwith 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 Structural Bolts in 7/8″ diameter are built for high-strength steel-to-steel bolting applications. Designed to meet ASTM F3125 standards, these heavy hex bolts provide secure, load-bearing connections in infrastructure, commercial construction, and industrial steel assemblies.

7/8″ A325 Type 1 Heavy Hex Structural Bolts for Bridges, Frames, and Heavy-Duty Steelwork

These bolts feature a 9 TPI coarse thread and a plain finish, ideal for environments where corrosion resistance isnt required but structural integrity is essential. The carbon steel construction offers dependable tensile strength, making them a go-to option for structural steel fabricators, contractors, and OEMs working on critical connections like I-beams, flanges, and support systems.

Key Features

• 7/8″ Diameter Carbon Steel: Delivers high tensile strength for heavy-load connections.
• A325 Type 1 Compliance: Meets ASTM F3125 specifications for structural bolting.
• 9 TPI Coarse Thread: Ensures tight, vibration-resistant engagement in steel-to-steel joints.
• Heavy Hex Head Design: Provides greater clamping force and larger bearing surface area.
• Plain Finish: Ideal for indoor or temporary structural installs where corrosion resistance is not required.
• Standard SAE Measuring System: Compatible with common tools and fasteners in U.S. applications.
• Common Uses: Structural framing, bridge construction, column anchoring, and steel fabrication.

Common Applications

• Structural steel connections in bridges and commercial buildings
• Steel beam and girder assembly for infrastructure projects
• Heavy-duty fabrication of industrial steel frameworks
• High-strength bolting in transportation structures and overpasses
• Steel-to-steel joints in construction requiring precise torque control

Installation Tips

• Pair with nuts and hardened washers of the same finish for correct thread engagement and load distribution
• Use torque methods approved by ASTM or AISC standards, typically turn-of-nut or calibrated wrench methods
• Inspect all components for damage or corrosion before assembly to ensure structural integrity
