    Used on heavy equipment, such as plows, these bolts have a smooth, flat head that's angled underneath to sit flush within countersunk holes. A square neck keeps them from turning when tightening a nut. The zinc plating provides corrosion resistance in wet environments. Material meets SAE J429 specifications for quality. Dimensions meet ASME B18.9 specifications. Length is measured from the top of the head. Head height includes the neck.

    These bolts have a thicker, domed head that provides greater wear resistance than flat head bolts. Used on heavy equipment, such as plows, these bolts are angled under the head to sit nearly flush within countersunk holes. A square neck keeps them from turning when tightening a nut. The zinc yellow-chromate plating provides corrosion resistance in wet environments. Material meets SAE J429 specifications for quality. Length is measured from the base of the oval top. Head height includes the neck and oval top.
