Connection systems

Structural Bolts
sourcing support.

Specification-led sourcing for structural fastening projects where connection design, assembly method and documentation must be confirmed.

Specification first

What to define for structural bolts.

Built for Structural steel procurement teams and construction distributors. Availability and compliance are confirmed only against a complete RFQ and the selected manufacturing source.

Applications

Where the category may fit.

Application context helps frame the RFQ; it does not replace engineering selection, approval or the governing project specification.

  • Structural steel connections
  • Construction projects
  • Engineered connection systems

Buyer brief

Start with the connection system and project standard; a general hex bolt should not be relabeled as structural.

A category page helps structure the conversation; the selected source and project documents still control the final requirement.

Watch point

ASTM F3125 and EN 14399 are separate project references. The engineer and project documents control the accepted system.

Include in the RFQ

  • ASTM or EN system, grade and assembly method
  • Bolt, nut and washer set requirements
  • Traceability, conformity documents, inspection and lot identification
