Hot Dip Galvanizing Pigtail Bolt Square Washer Nut Forged Fastener for Overhead Line Hardware Direct From Factory in Hebei China

A hot-dip galvanized pigtail bolt assembly with square washer and nut, designed for secure and reliable fastening in overhead power line systems. The forged construction and corrosion-resistant coating ensure durability and long-term performance in demanding environments.

Jiujin Electric Power’s Pigtail Bolt Assembly is a critical fastener engineered for overhead line hardware applications. Forged from high-tensile steel and protected with a heavy-duty hot-dip galvanized coating, this assembly offers exceptional strength and resistance to corrosion, rust, and environmental degradation. The unique pigtail (eye) end provides a secure attachment point for guy wires, insulators, and other components, while the square washer prevents rotation during installation and distributes load evenly. The precision-cut threads ensure easy engagement with nuts, maintaining consistent torque and clamping force. Produced at our Hebei factory, this fastener meets rigorous industry standards for electrical infrastructure, telecommunication, and construction projects.
