1/2″ x 6″ Conquest A325 Type 1 Heavy Hex Structural Bolt with 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 1/2″ diameter are engineered for steel-to-steel fastening in structural applications. These bolts meet ASTM F3125 standards, providing the strength and reliability required for bridges, commercial framing, and infrastructure work.

1/2″ A325 Type 1 Structural Hex Bolts for Beams, Frames, and Steel Assemblies

With 13 TPI coarse threads and a heavy hex head, these bolts offer solid clamping force and durability. The plain finish is suitable for controlled environments or temporary installations where corrosion resistance isnt a priority. Built from carbon steel, these bolts are widely trusted in construction and steel fabrication.

Key Features

• 1/2″ Diameter Carbon Steel: Suitable for structural load-bearing in steel assemblies.
• ASTM A325 Type 1 Certified: Meets F3125 standards for steel-to-steel structural connections.
• 13 TPI Coarse Thread: Offers secure engagement for vibration-resistant connections.
• Heavy Hex Head: Provides increased surface contact for stronger fastening torque.
• Plain Finish: Best for dry, interior, or non-corrosive settings.
• Standard SAE Sizing: Compatible with standard fasteners and tools.
• Used In: Bridge framing, structural steel builds, steel fabrication, and industrial construction.

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
