中国河北省杆线五金直销工厂热浸镀锌双臂螺栓

Hot-dip galvanized double arming bolts designed for robust and reliable fastening of crossarms to utility poles. Manufactured from high-tensile steel with superior corrosion resistance, these bolts ensure long-term structural integrity and safety in electrical distribution systems.

Jiujin Electric Power’s Double Arming Bolts are engineered to meet the demanding requirements of modern power distribution networks. Forged from high-tensile carbon steel and protected by a thick hot-dip galvanized coating, these bolts offer exceptional strength and resistance to rust, corrosion, and environmental degradation. The double-ended design facilitates symmetrical installation, distributing clamping force evenly to prevent wood splitting or metal fatigue in poles and crossarms. Precision-machined threads ensure secure fastening and ease of assembly, even under extreme weather conditions. Produced with strict quality control at our Hebei factory, these bolts provide reliable performance for utility, telecommunications, and infrastructure projects worldwide.
