Galvanized Pigtail eye Bolt for Electric Power Fittings
Galvanized Pigtail eye Bolt for Electric Power Fittings is also called pigtail eye bolt, pigtail hook, pigtail screw, pigtail hook screws, pigtail fastener, it’s one kind of pigtail hardware.
SMICO Galvanized Pigtail eye Bolt for Electric Power Fittings is designed for use on wooden poles, concrete or other power line poles to hang the dead end clamp or suspension clamp. Because the helical end of the pigtail bolt is like the “ pigtail”, so it was called a pigtail bolt or pigtail hook.
The pigtail bolt does not have the same shape and structure. The pigtail bolt used in Kenya and Zambia is a welded square washer or round washer on the neck of the pigtail hook. The pigtail bolt used in Malaysia has two extra forged points, on the left and right sides of the neck pigtail hook. This design prevents the washer from dropping off.
The complete set of a pigtail hook usually includes one piece of pigtail hook main body, two hex nuts, and two washers.
When the pigtail screw is installed on the wooden pole or concrete pole, the hex nuts and washers are used to fasten the end on one side of the pole. The other pigtail end is used to link the suspension clamp.
There is also a pigtail bolt without a screw, it’s only with a round end.
Compared to other pigtail eye bolt manufacturers, SMICO delivers a large variety of pigtail eye bolt designs to end-users, from varying rod diameter, thread length to structures. Jingyoung eyebolts are ideal for electric transmission, communication lines, and train lines.
SMICO pigtail eye bolt raw materials are steel rods. All the pigtail hooks are hot forged thus guarantees high breaking strength to load the overhead line accessories
The surface treatment is hot dip galvanized according to ISO1461

Pigtail bolts are among the primary fasteners in pole line transmission and distribution lines.
You will need a pigtail eye bolt when installing most pole line hardware
But, how do you find high quality, durable and reliable pigtail eye bolt?
In this guide, you will learn everything you need to look for – design, technical specifications, best material, etc.
Let’s get to that.
What is a Pigtail Bolt?
Pigtail eye bolt is used in concrete, wooden, and other power posts for receiving aerial bundled cable across suspension clamps and dead-end clamps.
These bolts have one end threaded for fitting of an expansion component.
The other end is hot worked to make a pigtail for the hanging of chain type handrails, electrical and telephone cable as well as air, refrigeration, water, and ventilation columns.
Benefits of Pigtail Bolts
Now, some of the main benefits of installing pigtail bolts include the following:
· Easy installation
For its installation, pigtail hook screws do not need a specific procedure.
This implies you can quickly put it into use immediately after its installation.
It performs its function without particular equipment or process.
· Use of simple tools
Possibly this is among the most essential advantages of using pigtail eye bolts as connectors.
It does not need distinct tools that call for know-how by a few.
· Accommodates minor measurement variations
Pigtail screws can integrate minor measurement differences.
The dimensions do not have to be precise in the event of slight dissimilarities in between.
· Immediate support
After attaching and tightening the pigtail bolt, it immediately holds the load irrespective of its weight.
· Negligible deformation
The bolts experience very insignificant buckling over time.
Applications of Pigtail Hook Screws
As I have stated already; you can use pigtail eye bolts for suspension of ventilation, air, refrigeration, and water columns as well as chain type handrails and telephone and electrical cable.
Using them for heavy duty applications such as supporting platforms and snatch block rigging is not advisable.
Main Components of Pigtail Bolts
The complete kit of pigtail hook normally compose of:
Single piece of pigtail bolt main body
Two hex nuts and
Two washers
There also exist some types of pigtail eye bolts without screw; they have a circular end.
· Threads
All threads formation is through a cold-rolling process, with the pigtail eye created by hot forming to boost its mechanical features.
Metric (right hand only) – M20 x 2.5 – 8g and M16 x 2 – 8g are the standard types of threads available.
However, the pigtail hook screws do not have similar shapes and structures.
Those widely used in Zambia and Kenya have circular or square washer welded on the bolt’s neck.
The commonly utilized pigtail hooks in Malaysia have two additional forged points on the right and left sides of the bolt’s neck.
This design type hinders the falling off of the washer.
Technical Specification of SMICO Pigtail Bolts
We provide our customers with pigtail bolts in several designs, from varying thread length, rod diameter to structures.
We manufacture our pigtail hooks using steel, and further hot forge them to promote high breaking strength necessary in overhead conduit connection.
The Production Process Summary
Uncoiling, straightening and cutting the wire to length.
Cold Forging: Forming the steel into the desired design at room temperature.
Pigtail end: Turning the bolt at high speed while twisting to obtain the pigtail design
Threading: Forming of threads is through cutting or rolling.
Heat Treatment: Hardening the steel by subjecting it to extreme heat.
Surface Treatment: Dependent on the use. Zinc-plating is popular to boost corrosion resistance. Jingyoung surface treats its pigtail eye bolts by hot-dip galvanization according to ISO1461.
Packing/Stocking: Packaging of the bolts after quality control to check uniformity and consistency.
Step-by-step-Pigtail Bolt Installation Process
You mostly use bolts to lock two or more items together via pre-drilled holes.
Washers help in reinforcing the connection by diffusing the force exerted by the pigtail bolt over a larger space.
Special washers are also there, for instance, lock washers, which assist in preventing coincidental unfastening of the pigtail screw.
Pigtail eye bolt aids in the fixing of suspension assemblies to the concrete or wooden pole.
Its installation is straightforward, by driving it through a pre-drilled hole and fastening with a nut.
After installing the pigtail hook screw on the concrete or wooden pole, you use the two hex nuts and washers to tighten its one end to the post.
The remaining pigtail end is where you connect the suspension clamp.
Pigtail hook has two nuts threaded onto it to fasten the joint, and similar to washers; they come in different kinds for a variety of uses.
The type used with pigtail bolts is hex nut.
Step 1
Establish the right size and type of nut, washer, and pigtail hook for your operation.
The choice is dependent on the kind of connection you are working on, the bolt strength, standards, and rules for the application among other factors.
Step 2
Insert the first washer on the pigtail bolt’s shaft.
You will add a lock washer if needed then follow it with the second washer.
Step 3
Push the pigtail hook screw through the hole, ensuring that you firmly press the first washer between the bolt neck and the pole.
Step 4
Insert the second washer on the part of the pigtail eye bolt that is protruding out from the pole.
Step 5
By twisting clockwise, thread the two hex nuts onto the pigtail fastener shaft.
Make sure the first nut presses on the washer by hand-tightening it.
Step 6
Using the correct size of wrench, fasten the nuts tightly against the washer, but do not overtighten.
