Yellow Zinc Plated Hitch Pins – 3/4 Diameter x 4-1/4 Inch Usable Length

Heavy-Duty Performance in a Compact, Corrosion-Resistant Package

Whether you’re locking in a trailer coupler, securing an agricultural implement, or connecting industrial machinery, you need hardware that holds up to repeated use, high loads, and tough environments. Our 3/4″ Diameter x 4-1/4″ Usable Length Yellow Zinc Plated Hitch Pin is designed for exactly that—reliability, durability, and ease of use.

Crafted from high-strength carbon steel and coated with a yellow zinc finish, this hitch pin delivers robust mechanical performance with excellent resistance to corrosion, wear, and vibration. It’s a dependable solution for trailers, utility vehicles, farm equipment, and more.

Key Features:

• 3/4-Inch Diameter Shaft
  Perfect for medium-duty applications, this pin size is widely used across a range of equipment types. It fits standard 3/4″ hitch holes snugly and securely, preventing excessive play and reducing wear on connected components.

• 4-1/4-Inch Usable Length
  The shaft offers 4-1/4 inches of usable length—ideal for securing couplers, tongues, drawbars, and various tow or implement setups. It provides enough clearance to accommodate thicker attachment points or dual-layer connections.

• Heavy-Duty Carbon Steel Core
  Manufactured from hardened carbon steel, this pin is engineered to resist bending, breaking, or shearing under heavy loads. Whether you’re pulling a fully loaded trailer or operating farm equipment, you can trust this pin to hold firm.

• Yellow Zinc Plated Finish
  The corrosion-resistant yellow zinc coating protects against rust, road salt, moisture, and chemical exposure. Ideal for outdoor and off-road applications, the finish also offers high visibility—making it easier to identify and remove in low-light or cluttered conditions.

• Locking Clip Included
  Each pin includes a high-strength steel hairpin or lynch pin clip to secure the pin in place. The clip slides in smoothly and holds tight, preventing accidental disengagement during transport or operation.

• Easy to Use – Glove-Friendly Design
  Designed for efficiency in the field, the pin features a formed head or pull ring (varies by style) for easy handling—even when you’re wearing gloves or working in dirty, wet conditions.

Common Applications:

• Utility and cargo trailers

• Lawn and garden equipment

• Agricultural implements (such as seeders, harrows, and plows)

• ATV/UTV tow connections

• Industrial carts and machinery

• General towing and fastening use

This versatile hitch pin is the go-to choice for medium-duty connection needs where reliability and quick, tool-free operation are essential.

• Road conditions involving salt or chemicals

• Long-term outdoor storage

• Heavy-use settings requiring repeated removal and reinsertion

Yellow zinc maintains a clean surface and doesn’t flake or chip as easily, ensuring a long service life and smooth pin operation.
