Plain A325 Structural Hex Bolts

Plain A325 Structural Hex Bolts are a go-to solution for structural steel connections in construction and industrial applications. These bolts are engineered to meet ASTM A325 specifications, providing reliable performance in demanding environments like bridges, high-rise buildings, and heavy equipment assemblies. With a plain (uncoated) finish, these bolts are ideal for indoor use or environments where protective coatings aren’t required.

Dependable Strength for Structural Steel Connections

Designed for high-strength bolted connections, these bolts are made from medium carbon steel that’s been heat-treated for enhanced strength and durability. They are commonly used with heavy hex nuts and structural washers to secure steel-to-steel connections. Their plain finish makes them a cost-effective choice for enclosed or interior applications where corrosion resistance isn’t critical.

Key Applications:

  • Steel building frameworks
  • Bridge and infrastructure construction
  • OEM and heavy equipment assemblies
  • Pre-engineered metal buildings

Features & Benefits:

  • ASTM A325 Compliance: Manufactured to meet strict industry standards for structural steel fasteners.
  • Heavy Hex Head: Offers a larger bearing surface for better clamping force in high-load applications.
  • Plain Finish: Suitable for indoor or low-exposure environments where corrosion resistance isn't a primary concern.
  • High Shear and Tensile Strength: Trusted by contractors and engineers for critical load-bearing connections.
  • Wide Selection: Available in multiple diameters and lengths to suit your specific project needs.
