Rugged Performance: Heavy Duty Hitch Pins for Safe Towing

Our Hitch Pins are engineered for the demanding world of towing and agriculture. A Trailer Hitch Pin is more than just a piece of steel; it’s the critical link between your vehicle and your load. Our pins are forged from high-strength alloy steel, ensuring they meet or exceed towing capacity ratings for Class I through Class V hitches. Whether you’re towing a boat, a horse trailer, or heavy farm equipment, our pins provide the peace of mind you need.

Available in the industry-standard 1/2 inch and 5/8 inch diameters, each pin is finished with premium coatings to prevent rust even in harsh road-salt environments.

Engineered for Maximum Safety

  • High Shear Strength: Heat-treated steel bodies designed to handle dynamic loads without bending or snapping.
  • Ergonomic Bent Handle: The 105-degree bend provides a comfortable grip, making it easy to install and remove even when wearing heavy gloves.
  • Superior Corrosion Protection: Choose from Zinc Plated, Chrome, or Black Powder Coating for long-lasting protection against moisture and debris.
  • Secure Retaining Hole: Precision-drilled to accommodate standard R-clips (Hairpin Cotters) or Linch Pins for a fail-safe lock.

Hitch Pins FAQ

Q: What is the difference between a 1/2″ and 5/8″ Hitch Pin?
A: A 1/2 inch pin is used for smaller 1-1/4″ receivers (Class 1 & 2), while a 5/8 inch pin is the standard for 2″ and 2-1/2″ receivers (Class 3, 4, & 5) used on most trucks and SUVs.

Q: Should I use a locking hitch pin?
A: If you leave your hitch ball mount on your vehicle, a Locking Hitch Pin is highly recommended to prevent theft. For agricultural use, a standard pin with a Linch Pin is often preferred for speed.
