Designed for robust support in heavy-duty applications, double-arming bolts effectively "unitize" two crossarms, ensuring the necessary strength for double arm construction. Commonly referred to as DA Bolts in the industry, these components are RUS listed and comply with ANSI standards, reflecting their reliability and durability. Crafted from galvanized steel per ASTM A-153, they boast an impressive rated tensile strength of 12,400 lbs, making them well-suited for demanding environments. Included with four square nuts for secure installation, these full-thread bolts feature cone pointed ends for easier fastening, ensuring that your aerial hardware setup can withstand the rigors of operation while maintaining structural integrity.
