Structural Bolts
Structural bolts are heavy-duty, high-strength fasteners engineered specifically for joining structural steel components in load-bearing construction and infrastructure applications. Blue Ribbon Fastener supplies ASTM-compliant structural bolts — including A325 and A490 grades — in heavy hex configurations with plain and hot dip galvanized finishes. Whether you're sourcing for a single job or managing an ongoing supply program, we offer same-day shipping on in-stock sizes and competitive volume pricing for contractors, fabricators, and distributors.
Usages for Structural Bolts
Structural bolts are specified for steel-to-steel connections in buildings, bridges, transmission towers, crane rails, and heavy industrial frameworks. They are installed using torque-controlled, turn-of-nut, or direct tension indicator (DTI) methods as required by RCSC specifications. A325 bolts are the most widely used specification for building construction, while A490 bolts are specified for higher-strength connections. Both are used in slip-critical and bearing-type joint configurations.
Structural Bolts for all Industries
Structural bolts are essential across commercial and industrial construction, civil engineering, transportation infrastructure, energy, and industrial fabrication. General contractors, steel erectors, and structural fabricators rely on consistent supply and proper ASTM certification for every project phase. Blue Ribbon Fastener serves customers in construction, bridge and highway infrastructure, utility and energy, industrial plant construction, and contract fabrication — providing certified structural fasteners with the documentation procurement teams require.
