A long shank crossarm pin is an insulator mounting fitting installed through a wood crossarm.

Instead of connecting two crossarms together, the pin provides a vertical mounting point for a compatible pin-type or spindle-threaded insulator.

The lower shank passes through the crossarm, while the upper section supports the insulator.

A broad base sits against the crossarm and helps distribute the mechanical load over a larger area.

You may also see this product described as:

  • Crossarm pin
  • Cross arm pin
  • Nylon crossarm pin
  • Insulator pin
  • Crossarm insulator pin
  • Pole line insulator pin
  • Long shank nylon crossarm pin

Although these names describe similar hardware, always confirm the shank diameter, shank length, insulator thread, height above crossarm, and supplied hardware before ordering.

What Does a Crossarm Pin Do?

The main function of a crossarm pin is to support and position a compatible insulator on a utility crossarm.

In an overhead distribution line, the conductor sits on or connects to the insulator.

Therefore, the crossarm pin forms an important mechanical connection between:

Conductor → Insulator → Crossarm Pin → Crossarm → Utility Pole

A correctly selected pin helps maintain the intended insulator position while transferring mechanical load into the crossarm.

Key Features of the CW-LCP Long Shank Crossarm Pin

One-Piece Steel Construction

The main crossarm pin is formed from steel as an integral component.

A one-piece structure avoids unnecessary welded joints in the main load-bearing pin.

This design provides a stable mounting point for the insulator and crossarm hardware.

Nylon Alloy Insulator Thread

The upper section uses a nylon alloy thread designed to interface with a compatible spindle-threaded insulator.

The nylon component provides a defined seating surface between the metal pin and insulator.

Before ordering, confirm the required insulator thread dimensions according to your insulator specification or utility drawing.

Broad Load-Distributing Base

The pin includes a broad base that sits against the wood crossarm.

This larger contact area helps distribute mounting load instead of concentrating pressure around a small section of the wood.

As a result, the design helps create a stable seat for the crossarm pin.

Square Wrenching Shoulder

A square shoulder above the base allows installers to hold or rotate the pin during installation and insulator positioning.

This feature can make final alignment easier when you need to orient the insulator correctly.

Hot-Dip Galvanized Steel Components

The steel pin and compatible metal hardware receive a hot-dip galvanized finish.

The zinc coating helps protect the steel against corrosion caused by outdoor exposure.

For utility tenders, always send your required galvanizing standard, coating requirement, or inspection specification before ordering.

Complete Long Shank Hardware Set

Long shank crossarm pins can be supplied with:

  • Square washer
  • Square nut
  • Concave MF locknut

These components help secure the pin through the wood crossarm.

Confirm the exact washer and nut dimensions when you request a quotation.

  • 6″ × 6-1/2″

Because crossarm pin dimensions can refer to different points on the pin, you should confirm the complete dimensional drawing before placing a bulk order.

For an accurate quotation, provide the required:

  • Shank diameter
  • Shank length
  • Height above crossarm
  • Insulator thread
  • Thread length
  • Base diameter
  • Washer dimensions

Where Are Long Shank Crossarm Pins Used?

You mainly use a long shank crossarm pin in overhead electrical distribution systems.

Typical applications include:

  • Wood utility pole crossarms
  • Overhead distribution lines
  • Pin-type insulator mounting
  • Spindle-threaded insulators
  • Rural electrification projects
  • Utility distribution networks
  • Pole line construction
  • Replacement and maintenance projects

The long shank passes through the crossarm and provides sufficient length for the washer, nut, and locking hardware underneath.

How Do You Choose the Right Long Shank Crossarm Pin?

Several dimensions affect compatibility.

1. Confirm the Shank Diameter

CW-LCP models are available in:

5/8″ and 3/4″

The correct diameter depends on the crossarm hole, utility specification, insulator load, and project drawing.

Do not substitute one diameter for another without engineering approval.

Long Shank Type Crossarm Pins

2. Confirm the Shank Length

The shank must pass through the crossarm and provide enough space for the washer, nut, and locknut.

Therefore, first measure the wood crossarm thickness.

Then compare it with the required pin dimensions.

3. Check the Height Above the Crossarm

The upper pin height affects the final insulator position.

Different pole line designs may specify different heights depending on conductor clearance and construction geometry.

Always follow the utility drawing.

4. Match the Insulator Thread

This is one of the most important selection points.

The nylon thread on the crossarm pin must fit the threaded hole of the insulator.

Provide the insulator drawing or thread specification when requesting a quote.

5. Check the Washer and Nut

The square washer distributes the tightening load against the wood crossarm.

Confirm:

  • Washer dimensions
  • Washer thickness
  • Nut type
  • Locknut type
  • Thread compatibility

This is particularly important when you replace an existing utility standard component.

6. Provide the Required Standard

Different utilities may specify requirements for:

  • Product dimensions
  • Steel material
  • Mechanical performance
  • Galvanizing
  • Insulator thread
  • Washer size
  • Nut dimensions
  • Inspection
  • Packing
  • Identification

If your project references ANSI C135.17 or another utility standard, send the complete requirement with your RFQ so Hbcrownwealth can confirm the requested configuration before production.

How Do You Install a Long Shank Crossarm Pin?

Installation should follow the utility construction drawing.

A typical installation follows these steps.

First, confirm that the crossarm hole matches the specified pin diameter.

Next, insert the long shank crossarm pin through the prepared hole.

Position the broad pin base firmly against the upper surface of the crossarm.

Then install the square washer, square nut, and locking hardware underneath the crossarm.

Tighten the assembly according to the required installation procedure.

After securing the pin, install the compatible threaded insulator onto the nylon thread.

Finally, check that:

  • The pin remains vertical
  • The base sits flat against the crossarm
  • The washer sits correctly
  • Nuts are fully engaged
  • The insulator thread seats correctly
  • The insulator is correctly oriented
  • No component shows visible damage

Do not force an incompatible insulator onto the nylon thread.

Why Does Hot-Dip Galvanizing Matter?

Crossarm pins remain outdoors throughout their service period.

Rain, humidity, condensation, temperature cycles, and pollution can accelerate corrosion on untreated steel.

Hot-dip galvanizing creates a zinc coating on the steel surface.

Therefore, it provides important corrosion protection for pole line hardware.

If your project requires compliance with a particular ASTM A153/A153M coating category, coating thickness, or inspection requirement, provide the exact specification before mass production.
