Introduction to Pig Tail Bolt
Pig Tail Bolt, also known as Pigtail Connector Bolt or Pigtail Fastener, is a specialized electrical fastening component widely used in overhead power lines, distribution networks, and electrical installation projects.
The unique spiral tail design provides flexible installation and reliable wire fixing performance, making it an important accessory for power line construction.
Pig Tail Bolts are usually manufactured from materials such as galvanized steel, stainless steel, copper, and aluminum to meet different requirements for mechanical strength, electrical conductivity, corrosion resistance, and outdoor durability.
What Is a Pig Tail Bolt?
A Pig Tail Bolt is a specially designed bolt with a curved or spiral‑shaped end.
Unlike standard bolts, the pigtail structure allows conductors or electrical components to be positioned and fixed more efficiently.
The unique design provides:
- Easy installation
- Secure connection
- Strong mechanical holding force
- Long‑term reliability
