Pigtail Bolts: The Essential Hardware for Power Line and Utility Poles

Pigtail bolts, also known as pigtail eye bolts, are a crucial component in the construction and maintenance of power lines, communication towers, and utility poles. These specialized fasteners offer a unique design that provides secure and efficient connections for various applications. In this article, we will delve into the world of pigtail bolts, exploring their design, benefits, and installation process to help you understand why they are an indispensable tool in the industry.

Design and Structure:

Pigtail bolts are characterized by their distinctive helical end, which resembles a pigtail, hence the name. This design allows for easy attachment of suspension clamps and dead-end clamps on wooden or concrete poles. The bolt's main body is typically made from steel rods, which are hot forged to ensure high breaking strength and durability. The threads are formed through a cold-rolling process, and the pigtail end is created by hot forming, enhancing its mechanical features.

Benefits of Pigtail Bolts:

Easy Installation: Pigtail bolts can be quickly installed without the need for complex procedures or specialized equipment, making them ideal for fast and efficient projects.

Simple Tools: The installation of pigtail bolts requires only basic tools, such as a wrench, making them accessible for a wide range of professionals.

Accommodates Variations: These bolts can easily integrate minor measurement differences, ensuring a secure fit even when exact measurements are not possible.

Immediate Support: Once installed and tightened, pigtail bolts provide immediate support to the connected components, regardless of their weight.

Minimal Deformation: Over time, pigtail bolts experience very little buckling, ensuring long-term stability and reliability.

Applications:

Pigtail bolts are widely used in the suspension of ventilation, air, refrigeration, and water columns, as well as for chain type handrails and telephone and electrical cables. They are also essential for supporting platforms and snatch block rigging in heavy-duty applications.

Installation Process:

Select the appropriate size and type of nut, washer, and pigtail bolt for your project.

Insert the first washer onto the bolt shaft, followed by a lock washer if necessary, and then the second washer.

Push the pigtail bolt through the pre-drilled hole, ensuring the first washer is firmly pressed against the pole.

Place the second washer on the protruding part of the bolt.

Thread the two hex nuts onto the bolt shaft, hand-tightening the first nut against the washer.

Tighten the nuts securely using the correct size wrench, avoiding overtightening.

Conclusion:

Pigtail bolts are a versatile and reliable fastening solution for a variety of applications in the power line and utility pole industry. Their unique design, ease of installation, and durability make them an essential component for any project requiring secure and efficient connections.
