Carriage Bolts

837 products

Carriage bolts feature a square or ribbed neck underneath the head of the fastener and typically a round head for smooth surface finishes. The square and ribbed necks secure the bolt to prevent it from turning when the nut is installed or removed. Carriage bolts are typically used to bond wood to wood, wood to metal, and occasionally metal to metal.
