Why Choose A325 Structural Heavy Hex Bolts?

Our A325 structural heavy hex bolts at AlbanyCountyFasteners.com, also known as A325 heavy hex bolts, are high-strength bolts designed for structural steel connections, meeting ASTM A325 specifications. Featuring a larger, thicker hexagonal head than standard bolts, they provide superior load distribution for heavy-duty applications. Made from medium carbon or alloy steel, these bolts are available in plain finish for indoor use or hot-dipped galvanized for corrosion resistance in sheltered environments. Available in imperial sizes like 1/2"-13, 3/4"-10, and 1"-8, they are typically paired with A563 heavy hex nuts and comply with ASME B18.2.1, IFI tolerances, REACH, and RoHS standards. Ideal for bridges, buildings, and infrastructure projects, these bolts ensure reliable, high-strength fastening.

  • High Strength: Meets ASTM A325 for robust structural performance.
  • Corrosion Resistance: Hot-dipped galvanized option for sheltered environments.
  • Enhanced Load Distribution: Larger head for greater bearing surface.
  • High Standards: Compliant with ASME B18.2.1 for dependable fastening.

Applications for A325 Structural Heavy Hex Bolts

A325 heavy hex bolts are engineered for high-strength structural steel connections, often used with A563 nuts to secure critical components in demanding environments. Their versatility makes them suitable for:

  • Bridge and highway construction
  • Steel building frameworks
  • Heavy industrial structures
  • Infrastructure and wind turbine assemblies

Frequently Asked Questions (FAQ)

What are A325 structural heavy hex bolts?

A325 structural heavy hex bolts are high-strength bolts with a larger, thicker hexagonal head, designed for structural steel connections, meeting ASTM A325 specifications.

How do A325 structural heavy hex bolts differ from A490 bolts?

A325 bolts are designed for general structural applications with high strength, while A490 bolts offer higher strength for more demanding structural connections, both meeting distinct ASTM standards.

Are A325 structural heavy hex bolts suitable for marine environments?

Hot-dipped galvanized A325 bolts provide corrosion resistance for sheltered environments, but for marine settings, 316 stainless steel or silicon bronze bolts are recommended.

How do I install A325 structural heavy hex bolts?

Thread the bolt through the materials, pair with an A563 heavy hex nut, and tighten with a torque wrench to the specified tension, ensuring proper alignment to avoid cross-threading.

How do I choose the right size A325 structural heavy hex bolt?

Select based on the thread size, such as 1/2"-13, 3/4"-10, or 1"-8. Ensure the bolt’s diameter, length, and thread pitch match the application and nut for secure fastening.
