Type: High Voltage Insulator Pin
Application: Overhead Distribution Lines / Utility Crossarms
A high voltage nylon thread crossarm pin is a pole line fitting that provides a mechanical mounting point for a compatible pin-type insulator on a utility crossarm.
You install the steel pin on the crossarm and then screw the insulator onto the nylon-threaded upper section.
The pin does not join two crossarms together.
Instead, it supports the insulator and transfers mechanical force from the conductor and insulator into the crossarm structure.
A simplified load path is:
Conductor → Insulator → Nylon Thread → Steel Crossarm Pin → Crossarm → Utility Pole

Although these terms describe similar hardware, you should always confirm the exact thread, shank, height, and mounting dimensions before ordering.
The main purpose of a high voltage crossarm pin is to mount a compatible spindle-threaded insulator on an overhead distribution crossarm.
Typical applications include:
The actual system voltage depends on the complete insulator and line design.
Therefore, you should not select the CW-HCP only because it carries the term “high voltage.” Instead, confirm the insulator specification and utility construction drawing.
The main pin uses an integral forged steel structure.
This construction creates a strong mechanical connection between the mounting shank, supporting base, and insulator pin section without relying on welded joints in the primary pin body.
For utility tenders, you can specify the required steel grade and mechanical performance according to your drawing.
The upper section uses a nylon alloy thread that interfaces with the threaded cavity of a compatible insulator.
Compared with an exposed metal-to-insulator interface, the nylon thread provides a firm but resilient seating surface for the insulator.
However, thread compatibility is critical.
Before ordering, you should confirm:
If you already use a particular pin-type insulator, send its drawing or sample with your RFQ.
The CW-HCP uses a broad base between the upper pin section and mounting shank.
The larger contact area helps distribute mechanical load at the crossarm mounting point.
This design also provides a more stable seating surface for the pin.
Correct base dimensions become particularly important when the crossarm carries mechanical forces from the conductor and insulator.
A square shoulder provides a convenient surface for holding or rotating the pin during installation.
As a result, installers can position the pin and insulator correctly before completing the final assembly.
The steel components receive a hot-dip galvanized surface treatment.
The zinc coating helps protect the steel against rain, humidity, condensation, and other outdoor environmental conditions.
For projects that specify ASTM A153/A153M or another galvanizing requirement, send the exact coating category and inspection requirement with your RFQ.

CW-HCP models can be manufactured in different dimensional configurations according to the required crossarm and insulator system.
When requesting a quotation, please identify each dimension clearly on your drawing, including:
Because similar numerical dimensions can refer to different parts of a crossarm pin, a dimensional drawing provides the most reliable basis for quotation and production.
The nylon thread forms the interface between the steel pin and the threaded insulator.
This design provides several practical benefits.
A properly matched nylon thread creates a secure seating surface for a compatible insulator.
The resilient material can accommodate the insulator interface while maintaining a firm fit.
The nylon component can tolerate handling and installation impact better than some traditional brittle thread materials.
Manufacturers can control the molded nylon thread dimensions to provide consistent fit between production batches.
However, this benefit depends on accurate tooling and quality control.
Different nylon thread configurations can also help distinguish pin specifications when a utility uses several insulator systems.
Nevertheless, you should always verify dimensions rather than relying only on appearance.
Both fittings mount insulators on crossarms, but their dimensions and insulator interfaces may differ.

| Nylon thread | Primary feature | Depends on model |
| Pin dimensions | Designed for specified utility configuration | Varies |

The term high voltage does not by itself define the electrical voltage rating of the complete system.
The insulator, conductor spacing, crossarm geometry, clearances, pollution level, and utility design all contribute to the actual electrical rating.
Therefore, always follow your project specification.
Different utility insulators may require different nylon thread sizes.
In the pole line hardware market, high voltage crossarm pins can be produced with different nylon thread diameters, including configurations designed around 1″ or 1-3/8″ insulator interfaces.
However, you should not assume that these two thread sizes are interchangeable.
Before ordering, verify:
If your existing insulator specifies a 1″ or 1-3/8″ interface, provide the complete insulator drawing so Hbcrownwealth can confirm the matching CW-HCP configuration.
Hbcrownwealth supplies several types of crossarm pins for different utility applications.
| Type | Main Selection Factor | Typical Application |
| Long Shank Crossarm Pin | Greater mounting depth | Thick wood crossarms |
| Short Shank Crossarm Pin | Shorter mounting section | Steel crossarms |
| High Voltage Nylon Thread Crossarm Pin | Insulator thread and utility design | High-voltage-type pin insulator mounting |
These categories can overlap in some designs.
For example, a high voltage nylon thread pin may also use a long shank configuration.
Therefore, always select the product according to the complete dimensions rather than relying only on the product category name.
The insulator is one of the most important selection factors.
Confirm:
A crossarm pin with an incorrect nylon thread may not seat correctly.
CW-HCP products are available with 5/8″ and 3/4″ shank options.
The correct diameter depends on the crossarm hole, mechanical requirement, and utility construction drawing.
Do not substitute the shank diameter without engineering approval.
The required shank length depends on the crossarm structure and mounting hardware.
For wood or composite crossarms, you may need a longer shank.
Other crossarm designs may use a different mounting depth.
Therefore, provide the crossarm thickness or complete drawing.
The upper pin height determines the final insulator and conductor position.
This dimension can affect conductor clearance and line geometry.
Always follow the utility drawing rather than selecting the pin only by overall length.
The nylon thread must match the insulator.
Provide the exact thread diameter and length or send the insulator specification.
This is especially important when your project uses a high voltage pin insulator with a specified spindle interface.
If your project specifies:
send these values with your RFQ.
Do not rely on product dimensions alone when the project specifies mechanical performance.
If your utility requires ASTM A153/A153M or another hot-dip galvanizing specification, send the complete requirement before production.
This allows the manufacturer to confirm the appropriate coating and inspection process.
Installation varies according to the crossarm and utility design.
First, confirm that the crossarm mounting hole matches the specified shank diameter.
Next, insert the crossarm pin into the correct mounting position and seat the broad base securely against the crossarm.
Then install the specified washer, nut, lockwasher, or other fastening hardware.
After tightening the pin according to the construction requirement, install the compatible insulator onto the nylon thread.
Finally, inspect the complete assembly.
Check that:
Never force an incompatible insulator onto the nylon thread.
