Structural Fasteners

Usages for Structural Fasteners

Structural bolts are used in steel building frame connections, bridge and overpass steel assemblies, tower and transmission structure bolting, crane and heavy equipment structural joints, and pre-engineered metal building erection. Heavy hex structural bolts are installed with matching heavy hex nuts and hardened washers to develop the clamping force required for slip-critical and bearing-type connections. Tension-control (TC) bolt assemblies feature a splined end that shears off at a calibrated torque, allowing ironworkers to verify proper installation tension in the field without a torque wrench.

Structural Fasteners for all Industries

Structural fasteners serve the commercial construction, industrial building, bridge and infrastructure, energy and utility, and steel fabrication industries. Structural engineers, steel detailers, general contractors, and erection crews source structural bolts as a code-specified item for connections designed to AISC and RCSC (Research Council on Structural Connections) standards. Blue Ribbon Fastener provides structural bolt assemblies in the grades and configurations most commonly specified, with certified material test reports available for structural inspection and documentation requirements.
