Product Description

Structural fasteners are strong, heavy-duty fasteners necessary for the construction of structures that include steel-to-steel connections. They are critical components used when one metal structure needs to be connected securely to another.

Fastener Application Fastener Types

The typical application of structural fasteners is in bridge and building construction, where they connect metal beams and girders. These fasteners are made of quenched and tempered steel to ensure maximum reliability under stress.

Commonly Used Structural Fasteners:

  • Heavy Hex Bolts: Larger and thicker than standard hex bolts, typically following A325 and A490 specifications.
  • Heavy Hex Nuts: Also known as finish nuts, providing both strength and a clean finished appearance.
  • Tension Control (TC) Bolts: Designed to handle vibrations, prevent load reversals, and eliminate slips in connections.
Key Selling Points
  • Load Distribution: Ensures even distribution of forces across the entire steel structure.
  • Structural Stability: Provides secure connections that resist environmental stresses and mechanical vibrations.
  • Durability: High-strength materials prevent wear and tear in critical structural joints.
  • Environmental Resistance: Hot-dip galvanizing provides superior protection against corrosion in extreme temperatures or humidity.
