Yellow Zinc Plated Linch Pin – 7/16 Diameter x 1-3/4 Inch Long with Ring

Secure Your Equipment with Confidence

When it comes to fast, reliable, and secure pinning solutions for trailers, agricultural equipment, and industrial machinery, the Yellow Zinc Plated Linch Pin – 7/16″ Diameter x 1-3/4″ Long with Ring is an essential tool every professional and DIYer should have. Crafted for durability, corrosion resistance, and ease of use, this linch pin ensures your components stay locked in place, even under vibration, heavy loads, and harsh environmental conditions.

What Is a Linch Pin?

A linch pin is a quick-release fastening device designed to prevent a wheel, clevis, or other component from sliding off a shaft or axle. It’s widely used in farming equipment, trailers, construction machinery, and countless other applications where safety and quick disassembly are crucial.

Unlike cotter pins or clips, linch pins are reusable, easy to install, and offer a reliable locking mechanism thanks to their integrated retaining ring. The ring snaps around the pin shaft, holding it firmly in place and preventing accidental disengagement.

Key Features:

• 7/16-Inch Diameter Shaft:
  This common diameter fits a wide range of hitch holes, clevis pins, shafts, and axles. The precise 7/16″ size offers a snug, secure fit that minimizes wear and ensures the parts stay connected firmly.

• 1-3/4 Inch Length:
  The shaft length is perfectly sized to accommodate medium-thickness mounting points, providing enough clearance for proper installation while maintaining strong holding power.

• Durable Yellow Zinc Plating:
  The bright yellow zinc finish provides superior corrosion resistance, protecting the steel core from rust, oxidation, and weather-related damage. This makes it ideal for outdoor use on trailers, farm equipment, and construction vehicles.

• Attached Retaining Ring:
  The spring-loaded ring locks securely around the pin shaft to prevent accidental release during operation. The ring also makes it easy to pull the pin out when you need to remove or adjust your equipment.

• Heavy-Duty Steel Construction:
  Made from hardened carbon steel, the pin offers excellent strength and resilience under repeated use and heavy stress. It withstands vibration, impact, and mechanical wear without bending or breaking.

• Reusable and Tool-Free Operation:
  The linch pin’s simple design allows for fast installation and removal without any tools. Just insert the pin through the hole and snap the ring over the shaft — no hammering or fiddling required.

Common Applications:

• Trailer hitch and coupler locking

• Securing agricultural implements like plows, seeders, and mowers

• Attaching accessories on tractors, ATVs, and utility vehicles

• Industrial equipment fastening

• Holding clevis pins in place for linkage or pivot points

• Any quick-release pin application requiring reliable, reusable fastening

Why Choose Yellow Zinc Plated Linch Pins?

The yellow zinc plating isn’t just for looks—it’s a high-performance protective finish that extends the life of your pin and reduces maintenance needs. Compared to plain steel pins, yellow zinc plated linch pins resist:

• Rust and corrosion in wet or humid environments

• Exposure to road salts and chemicals

• Fading and wear from UV exposure

• Surface damage from frequent handling and impact

The bright yellow color also makes these pins easy to spot in dim light or cluttered work areas, reducing the chance of losing critical fasteners on the job site.

How to Use Your Linch Pin:

1. Align the holes of the components you want to secure—such as a hitch and receiver or clevis and shaft.

2. Insert the linch pin through the aligned holes until the shaft passes completely through.

3. Rotate the retaining ring over the pin shaft until it snaps into place, locking the pin securely.

4. To remove, simply pull the retaining ring back and slide the pin out—no tools required.

Maintenance Tips:

• Keep the pin clean and free of dirt or debris for smooth operation.

• Inspect the retaining ring periodically to ensure it maintains spring tension.

• If exposed to harsh chemicals or salty environments, rinse and dry after use to preserve the zinc plating.

• Replace the pin if you notice excessive wear, bending, or if the retaining ring loses tension.
