You will find plow bolts primarily used in extreme conditions, such as heavy equipment, due to their industrial strength and increased wear resistance. Much like elevator bolts and carriage bolts, they have square necks to prevent the bolt from rotating when tightening. Fasteners Etc., Inc. offers grade 5 plow bolts with flat and dome head style. Plow bolts are offered in plain steel as well as zinc plated for increased corrosion resistance.
