Bulk 5/16"-18 Carriage Bolts Coarse Stainless Steel 18-8 (A2)

Corrosion-Resistant Fasteners for Secure and Reliable Connections

Enhance your construction, woodworking, and general maintenance projects with our premium 5/16"-18 Carriage Bolts made from 18-8 (A2) stainless steel. Offering solid corrosion resistance and strength, these bolts are ideal for both indoor and outdoor uses in moderate conditions.

Carriage bolts feature a smooth, domed head with a square neck beneath. The square neck design locks the bolt into a pre-drilled hole, preventing rotation as the nut is tightened from the opposite side. This design is ideal for wood-to-wood, wood-to-metal, and some light metal-to-metal applications, ensuring secure and tamper-resistant connections.
