Carriage Bolts

Usages for Carriage Bolts

Carriage bolts are used in wood-to-wood and wood-to-metal connections where the bolt must resist pull-through and the head must remain flush and snag-free on the accessible face. Typical applications include deck and dock construction, playground and recreational equipment, fence and gate hardware, timber framing connections, agricultural structures, and marine dock and pier construction. They are installed by pulling the square neck into the material with a nut and washer on the threaded end, eliminating the need for a wrench on the bolt head.

Carriage Bolts for all Industries

Carriage bolts are used across residential and commercial construction, landscape and recreational structures, marine and coastal applications, agricultural building, and furniture and fixture manufacturing. Contractors, builders, and maintenance crews who need a clean-head bolt for visible or contact-prone surfaces consistently choose carriage bolts. Blue Ribbon Fastener supplies carriage bolts in the volumes and finishes needed for both production and project-specific applications, with galvanized and stainless options for outdoor and corrosive environments.
