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.
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.
