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 too have square necks to prevent the bolt from rotating when tightening. Fasteners Etc., Inc. offers plow bolts as both grade 5 and grade 8 with flat and/or dome head style. If you need assistance with selecting the best bolt option for your project, call today!
