Bronze Square-Neck Carriage Bolts
Made from bronze, these bolts provide corrosion resistance to salt water, gases, and sewage, and are nonmagnetic and electrically conductive. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Dimensions meet ASME B18.5 specifications. Length is measured from under the head.
