Double-arming bolts play a crucial role in reinforcing the strength of crossarms during line construction, effectively allowing for a reliable "unitized" assembly when necessary. Designed with full-thread and cone pointed ends, these bolts ensure a secure fit, which is paramount in aerial hardware applications. Each set includes four square nuts, facilitating easy installation while meeting industry standards including ANSI C135.1 and CAO 6645. Boasting a remarkable rated tensile strength of 12,400 lbs, these galvanized bolts are built to withstand considerable forces, ensuring long-lasting durability. Their construction, compliant with ASTM A-153 specifications, means they resist corrosion and other environmental challenges, making them a dependable choice for any project that demands structural integrity in aerial line hardware applications.
