Product Description

Zinc Plated Steel Carriage Bolts

Carriage bolts feature a domed head, with the shank topped by a short square section under the head. This square section grips into the part being fixed, preventing the bolt from turning when the nut is tightened. Commonly used to fasten wood panels to masonry or to each other, these bolts also include a domed head for added style and functionality. The 307A Zinc plating provides an extra layer of corrosion resistance, as well as a shiny finish to the class 4.6 steel. Typically used with hex nuts, flat washers, and wood applications, these bolts are versatile and durable.
