Comprehensive Selection Of A325 And A490 Heavy Hex Fasteners
Our inventory includes high-strength fastening products manufactured to meet ASTM A325 and A490 specifications. These fasteners are heat-treated to ensure superior tensile strength and long-term reliability under extreme loads. We offer options from weathering steel and medium carbon alloy steel enhanced with copper, chromium, and nickel, providing excellent corrosion resistance for outdoor and marine environments. Both hot-dipped and mechanical galvanized finishes are available in accordance with ASTM B695, and a full range of sizes is ready for immediate shipment.
Fasteners Built For Strength, Reliability & Industry Compliance
Every fastener and piece of hardware we supply is designed for strength and reliability, making them ideal for on-site structural assembly connections where performance is critical, including the use of heavy hex structural bolts.
Our heavy hex head fasteners are engineered to promote even load distribution and reduce slippage during tightening, ensuring precise and secure bolting in demanding situations.
In addition to heavy hex fasteners, we offer a complete range of:
- Round head bolts
- Socket machine bolts
- Tension control bolts

What is Considered a Structural Bolt?
Structural bolts are essential in construction, engineered for joining heavy steel components and ensuring the stability of large structures.
Manufactured to ASTM A325 and A490 standards, these high-strength bolts reliably withstand significant tensile and shear forces, even in demanding environments. Their heavy hex design and robust construction make them ideal for outdoor, marine, and industrial applications, resisting galling and loosening under fluctuating conditions.
As a result, structural bolts play a critical role in maintaining the integrity and safety of bridges, high-rises, and other major infrastructure projects.
What is the Difference Between Grade 8 and Structural Bolts?
Grade 8 bolts and structural bolts each serve unique purposes in construction.
Structural bolts, built to ASTM A325 and A490 standards, are ideal for assembling large steel structures and excel in shear strength and durability under harsh conditions.
Grade 8 bolts, with a high tensile strength of 150 ksi and chromate plating, are mainly used in automotive and heavy equipment applications.
The choice between them depends on project requirements—tensile strength for Grade 8, or environmental resilience and shear strength for structural bolts—both offering exceptional performance when properly applied.
What is the Difference Between Type 1 and Type 3 Structural Bolts?
Type 1 and Type 3 structural bolts differ mainly in material and environmental suitability.
- Type 1 Bolts: Made from carbon or alloy steel, are ideal for indoor or controlled environments where corrosion resistance isn't critical.
- Type 3 Bolts: Made from weathering steel, form a protective rust layer, making them perfect for outdoor use and harsh weather conditions.
The choice depends on the project's exposure to the elements-Type 1 for standard applications, Type 3 for superior corrosion resistance in challenging environments.
Ultimately, this helps minimize maintenance, ensuring projects are structurally sound and durable over time.
