Hillman 812551 5/16x3 Carriage Bolt, 5/16 X 3-Inch, Galvanized

Most of our fasteners have a light zinc plating over steel giving a more rust resistant finish. We also sell coated and stainless products for additional rust resistance. We stock many grades of fasteners ranging from low carbon steel on up to hardened, heat treated steel. Not all fasteners are applicable for all applications so be certain to test thoroughly and get the opinion of a licensed building or certified building or structural engineer before relying on these fasteners for any situations where failure would result in damage to property or person.
