Designed to enhance structural integrity in line construction, double-arming bolts serve a crucial role in connecting two crossarms, effectively unitizing them for added strength. Commonly referred to as "DA Bolts" in the industry, these steel components are built to withstand a rated tensile strength of 12,400 lbs., ensuring reliability in demanding applications. They come equipped with four square nuts and are galvanized per ASTM A-153 standards for durability and corrosion resistance. Manufactured in accordance with ANSI C135.1 and CAO 6645, these full-thread bolts feature pointed cone ends, facilitating easier installation. Ideal for use in aerial hardware and poles, their robust design meets the rigorous demands of modern aerial line hardware applications.
