The Jiujin Double Arming Bolt is a fundamental component in utility pole construction, engineered to provide robust and reliable fastening of crossarms to wooden, concrete, or steel poles. Manufactured from high-tensile carbon steel and finished with a heavy-duty hot-dip galvanized coating, this bolt offers exceptional corrosion resistance, ensuring durability in harsh outdoor environments. The double-ended design allows for symmetrical nut placement, distributing pressure evenly across the crossarm and pole to prevent splitting or deformation. Precision-cut threads enable easy installation and consistent torque application, maintaining secure connections even under dynamic loads caused by wind, ice, or conductor tension. Produced at our Hebei factory, these bolts meet rigorous industry standards for strength, safety, and performance in power distribution networks.
