Material

The Carriage bolts kits are made of carbon steel with black coating, which have greater strength and corrosion resistance performance than regular zinc plated fasteners.

Feature

The carriage bolts have round heads and square necks. The square neck locks the square receiver hole to prevent rotation. The polished round head reduces surface protrusion and enhances the safety of connection and application.

Wide Application

The Carriage Bolts Kits can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are also suitable for pergolas, fences, decks, furniture, wood-working and other projects.
