USA Fractional Size A325 Type 1 Heavy Hex Structural Bolt with Plain Finish

USA Fractional Size A325 Type 1 Heavy Hex Structural Bolt with Plain Finish

The USA Fractional Size A325 Type 1 Heavy Hex Structural Bolt with Plain Finish is a premium high-strength fastener engineered for critical structural steel connections. Manufactured in the United States to meet strict ASTM A325 Type 1 standards, these heavy hex structural bolts are trusted by contractors, steel fabricators, and engineers for dependable performance in demanding load-bearing applications. When structural integrity and compliance matter, USA-made A325 bolts deliver proven reliability.

Produced from medium carbon steel and heat-treated to achieve required mechanical properties, these bolts are specifically designed for steel-to-steel structural joints in commercial, industrial, and infrastructure projects.

Manufactured to ASTM A325 Type 1 Specifications

A325 Type 1 heavy hex bolts are intended for use in pre-tensioned structural connections. The heavy hex head design provides a larger bearing surface than standard hex bolts, allowing improved load distribution and secure wrench engagement during installation.

Key Features and Specifications

• Fractional inch diameters for standard structural steel assemblies

• Heavy hex head for increased clamping force

• Heat-treated medium carbon steel construction

• Designed for use with hardened structural washers and heavy hex nuts

• Suitable for slip-critical and bearing-type connections

These bolts are engineered to perform under high tensile and shear loads, making them ideal for structural steel erection.

Plain Finish for Interior and Controlled Environments

The plain finish provides a clean, uncoated steel surface. This makes the bolt ideal for interior structural applications or projects where additional coatings, painting, or specialized treatments will be applied after installation.

Advantages of Plain Finish A325 Bolts

• Precise dimensional tolerances

• Consistent torque-tension performance

• Ideal for indoor structural framing

• Compatible with custom protective coatings

Common Structural Applications

USA Fractional Size A325 Type 1 Heavy Hex Structural Bolts with Plain Finish are widely used in:

• Commercial building frameworks

• Industrial plant construction

• Structural steel columns and beams

• Equipment platforms and mezzanines

• Infrastructure projects in protected environments

For projects requiring American-made quality, ASTM compliance, and high-strength fastening performance, these heavy hex structural bolts provide the durability and structural confidence professionals depend on.
