galvanized carriage bolts
Hot dipped galvanized carriage bolts are very corrosion resistant and are commonly used in outdoor and marine environments. Galvanized bolts can only be used with galvanized nuts due to the thickness of the coating.
Zinc Carriage Bolt
Low carbon steel, best for general use applications (comparable to Grade 2). Zinc Plating is the most common finish and provides moderate protection against corrosion.
Grade 5 Carriage Bolt Head Marking
Medium carbon steel, for higher strength applications. Zinc Plating is the most common finish and provides moderate protection against corrosion.
