What is a Pigtail Screw?
Pigtail Screw is a screw that usually has a unique spiral or curved design, similar to the shape of a pig's tail (hence the name "Pigtail"). This design allows it to better connect tightly to the target object during installation and enhance stability. Its threads can easily cut into the material and provide a strong grip. It is widely used to connect wires, fix parts or fix other structural parts.
Pigtail Screw can be a standard metal screw or made of stainless steel or other alloys as required, which has corrosion and oxidation resistance.
Types of Pigtail Screws
There are many types of Pigtail Screws, each type can be selected according to different uses and requirements. Here are some common types:
-
Standard Pigtail Screws: Usually used for general connection and fixing, suitable for most home or industrial purposes.
-
Stainless Steel Pigtail Screws: Suitable for humid or corrosive environments, such as seaside or chemical plants.
-
Copper Pigtail Screws: Used in electrical connections, especially when the electrical system requires good conductivity.
-
Plastic Coated Pigtail Screws: Suitable for electrical applications that require insulation to prevent short circuits or electric shock.
-
Galvanized Pigtail Hook Screws (PS-8): Hot-dip galvanized steel, engineered for aerial electrical lines and low-voltage cable tension on wooden poles, meeting NF C 33042 and EN 50-483 standards.
Each type of Pigtail Screw has its specific advantages, and the appropriate material and size should be selected according to the needs.

How to Install a Pigtail Screw
To install the Pigtail Screw, you can follow these steps:
1. Prepare the Tools
Make sure to use the appropriate screwdriver or power tool, and check that the size of the Pigtail Screw matches the target material.
2. Locate the Installation Position
Mark the installation position of the screw according to the part or material that needs to be fixed.
3. Screw in the Screw
Use a screwdriver or power tool to screw the Pigtail Screw into the material. Due to its spiral design, it will naturally cut in and fix tightly.
4. Check the Fixing Effect
Make sure the screw is fully screwed in and check whether the connection is firm and reliable. For safety-critical applications like aerial electrical work, load testing per relevant standards is recommended.
During the installation process, avoid excessive force to avoid damaging the material or excessive wear of the screw.

Maintenance Tips for Pigtail Screws
To extend the life of your Pigtail Screw and maintain its good performance, you can follow these maintenance recommendations:
Regular Inspection
Check if the screws are loose or worn, and tighten or replace damaged screws in time. In outdoor installations, check every 6–12 months.
Prevent Corrosion
Use anti-corrosion protectants to avoid rust, especially in humid or chemical environments. Re-coat galvanized screws if the zinc layer shows signs of wear.
Keep Dry
Keep the screws and their connection areas dry to avoid moisture accumulation that causes corrosion.
Clean the Screws
Clean the Pigtail Screw regularly to remove dust and dirt to prevent damage to its threads.
Load Verification
For high-tension applications (aerial lines, guy-wire anchoring), periodically verify that applied loads remain within design specifications.
FAQ: Common Questions About Pigtail Screws
What is a pigtail screw used for?
Pigtail screws are primarily used for aerial electrical cable anchoring, especially in low-voltage distribution systems where they secure ABC cables, anchor brackets, and tension clamps to wooden utility poles. They’re also used in construction scaffolding, mechanical equipment assembly, and general fastening applications requiring quick installation and reliable hold-strength.
What is the difference between a pigtail screw and a pigtail bolt?
Screws are inserted directly into wood with load capacity of 2–5 kN, while bolts require pre-drilled holes with load capacity of 16+ kN. Screws suit light-to-medium duty LV cable work; bolts suit heavy-duty HV transmission line dead-ends. Screws are more economical; bolts offer higher safety margins for critical infrastructure.
How do I install a pigtail screw?
Installation steps: Mark the installation point on the wooden pole or material. Use a screwdriver or hand/power drill to insert the screw. Rotate clockwise until fully seated—the spiral threads will cut naturally into the material. For cable applications, attach your cable clamp or sling to the hook eye. Verify the connection is firm and load-rated per your application requirements.
What size pigtail screw do I need?
Size depends on material thickness (ensure penetration of at least 2/3), load requirements (choose MBL ≥ 1.5× your application load), material type (wood poles typically use 6–10 mm diameter screws), and applicable standards (NF C 33042, EN 50-483, NEMA C136). Consult our technical team for custom sizing recommendations.
Can pigtail screws be used in outdoor aerial applications?
Yes, absolutely. Galvanized steel pigtail screws (like PS-8) are specifically engineered for outdoor weather exposure with excellent corrosion resistance. They’re certified for aerial LV cable anchoring per NF C 33042 and EN 50-483 standards, making them the standard choice for utility poles worldwide.
What materials are pigtail screws made from?
Common materials include carbon steel (standard, requires coating for outdoor use), galvanized steel (hot-dip or cold, for outdoor aerial lines), stainless steel (superior corrosion resistance in coastal/chemical environments), copper/brass (for electrical applications requiring low resistance), and plastic-coated variants (for electrical isolation). Choose based on environmental exposure and electrical requirements.
Are pigtail screws standards-certified?
Yes. Quality pigtail screws meet international standards including NF C 33042 (French aerial electrical line equipment), EN 50-483 (European LV overhead distribution equipment), NEMA C136/ANSI C135 (North American utility pole hardware), and IEC 61235 (International overhead line hardware). Always request certification documentation when sourcing from suppliers.
How do I choose between pigtail screw manufacturers?
Key factors: quality assurance (in-house testing labs, third-party certifications), standards compliance (NF C 33042, EN 50-483), customization capability, reliable lead times, technical support for sizing and load calculations, and competitive bulk pricing.
