Its design features an internally threaded section measuring four inches long, paired with a three-inch externally threaded portion, ensuring compatibility with 5/8 in-11 bolts. Made from hot dip galvanized steel, this extension bolt not only meets ASTM Specification F2329 for durability but also provides excellent resistance to corrosion, making it an essential component for reliable suspension and attachment in aerial hardware setups.
