The REACON ASTM A153 Hot Dip Galvanized Pig Tail Bolt is a specialized pole line hardware component designed for wire attachment, guying support and cable anchoring applications in overhead electrical and communication networks.
Manufactured from steel and finished with a hot-dip galvanized zinc coating, this fastener combines a threaded mounting section with a curved pig tail end. The open-loop configuration provides a convenient attachment point for compatible wires, hooks and line fittings without requiring a conventional closed eye connection.
Unlike standard machine bolts or straight threaded fasteners, the pig tail bolt features a specially formed curved end that accommodates specific wire routing and attachment requirements. It is commonly selected for utility pole installations where a practical connection point is needed for supporting or securing overhead line accessories.
The product is available in different dimensions and structural configurations to accommodate various installation requirements. REACON also supports customized manufacturing according to customer drawings and project specifications.
For outdoor applications, hot-dip galvanizing in accordance with ASTM A153 helps protect the steel surface against corrosion caused by moisture and environmental exposure.

REACON provides different pig tail bolt configurations for utility, communication and outdoor structural applications.
1. Standard Pig Tail Bolt
The standard pig tail bolt features a threaded mounting section and a curved open-loop end.
The threaded section is used to secure the fastener to a compatible pole, bracket or mounting assembly, while the curved end provides an attachment point for suitable wires and fittings.
This configuration is commonly used in utility pole line support systems.
2. Pig Tail Eye Bolt
The pig tail eye bolt features a curved eye-shaped end designed to accommodate compatible wire loops, hooks and connecting accessories.
Its open-loop structure allows convenient attachment and removal of suitable fittings during installation and maintenance.
It is suitable for selected guying, suspension and cable support applications where the connection design requires a pig tail-shaped attachment point.
3. Heavy-Duty Pig Tail Bolt
Heavy-duty pig tail bolts are designed for applications requiring greater mechanical strength and more substantial structural dimensions.
The steel body, threaded section and curved end are manufactured according to the selected design requirements.
The appropriate configuration should be determined according to the working load, installation method and applicable engineering specifications.
4. Customized Pig Tail Bolt
Different utility projects may require specific dimensions and attachment configurations.
REACON can provide customized products according to customer drawings, including:
Overall bolt length.
Thread diameter and length.
Curved loop dimensions.

Pig tail bolts are used in several types of outdoor infrastructure where wire attachment and mechanical support are required.
1. Utility Pole Guying Systems
Pig tail bolts can provide attachment points for compatible guy wires and supporting fittings used in utility pole stabilization systems.
How to Apply:
• Confirm the required bolt dimensions and working load.
• Identify the designated mounting position on the utility pole or supporting bracket.
• Install the threaded section into the compatible mounting assembly.
• Secure the bolt using the specified nuts and washers where required.
• Attach the compatible guy wire or connecting fitting to the curved end.
• Check the connection and tension according to the project requirements.
2. Overhead Power Distribution Lines
In overhead distribution networks, pig tail bolts can be used as attachment components for selected line support and suspension assemblies.
How to Apply:
• Select a suitable product according to the installation drawing.
• Mount the threaded section on the designated pole hardware.
• Attach compatible hooks, wires or fittings to the curved end.
• Confirm that the attachment is correctly seated.
• Inspect the assembly before placing it into service.
3. Telecommunications and Fiber Optic Networks
Pig tail bolts can be used in selected communication pole installations for attaching messenger wire accessories and aerial cable support fittings.
How to Apply:
• Determine the required mounting location.
• Install the bolt on the designated pole bracket or support structure.
• Attach the compatible messenger wire fitting or cable support accessory.
• Verify the connection and cable routing.
• Check the assembly for proper mechanical stability.
4. Outdoor Industrial Structures
The product can also serve as a wire attachment point on suitable towers, lighting structures, steel frames and other outdoor installations.
How to Apply:
• Confirm the structural requirements and required attachment load.
• Select the appropriate bolt configuration.
• Install the threaded section on the prepared mounting structure.
• Connect the designated wire or support fitting.
• Inspect the fastening and attachment points before operation.
5. Pole-Mounted Hardware Assemblies
Pig tail bolts can be integrated into selected pole-mounted hardware arrangements where a curved attachment point is required.
Their configuration allows compatible line fittings and support accessories to be connected according to the assembly design.
Correct installation is essential for maintaining the mechanical performance of pig tail bolts.
Mounting Compatibility
Check the thread diameter, length and mounting structure before installation. The threaded section must match the designated mounting hole or supporting accessory.
Proper Fastening
