5/8" Hitch Pin

​​​​​​​5/8" Hitch Pin & Clip - Heavy-Duty Steel Bent Pin with Zinc Plating

Qingdao RuiRui's 5/8" Hitch Pin & Clip delivers enterprise-level fastening performance for Class III, IV, and V receiver applications. This bent-style joint is made of precision-machined steel with a 0.625-inch circle and a zinc-plated finish. Our 5.3-inch length design gives you better support and grip for heavy-duty pulling tasks. This professional-grade gear makes sure that tow cars and trucks can reliably connect. It is made to handle high shear forces of up to 10,000 lbs GTW. We have been making pins for more than 17 years and are ISO 9001:2015 certified. Each pin is made to exact measurements within ±0.005mm using our advanced CNC turning technology.

 Why Choose Our 5/8" Hitch Pin & Clip?

Superior Engineering Design

Your safety while pulling depends on how well the parts are made. When compared to straight pins, our bent-style pins are easier to place and give better grip. The 5.3-inch length gives you the best leverage while still being easy to store.

Premium Materials & Finish

For the strongest tensile strength, we use carbon steel that has been heat-treated. The zinc plating makes the metal very resistant to corrosion, which extends its useful life in tough conditions like sea and farming settings.

Precision Manufacturing

Our state-of-the-art CNC turning centers make sure that the width is always within 0.625 inches. To make sure they fit properly in 2-inch and 2.5-inch receivers, each pin goes through a strict quality check that includes CMM measurements and physical checks.

Proven Reliability

We know how important trailer connection gear is because we've been making things for more than 20 years. Vibrations can't make our pins open, and they stay in place reliably even when they're being loaded and unloaded quickly.

Applications & Use Cases

Heavy-Duty Recreational Towing

Great for keeping ball mounts in place when pulling boats, RVs, or equipment trailers. The strong construction can handle high speeds and rapid stops on the highway without putting safety at risk.

Commercial & Agricultural Operations

Perfect for attaching tools to tractors and keeping work gear safe. The finish won't rust when it comes in contact with chemicals, mud, and hard weather.

Off-Road & Recovery Applications

Important for attaching rescue gear and extras to trailer hitches. The high shear strength gives people trust when they are pulling vehicles out of trouble or doing rescue work.

Technical Advantages

Bent Design Benefits

The bent shape is better than straight pins in a number of ways. You have a better grip when taking it off, less chance of dropping it when putting it on, and more strength when working in small areas.

Optimal Diameter Selection

The standard in the business for heavy-duty uses is a 5/8-inch width. This size is just right for Class III, IV, and V transmitters because it is strong and works with them.

Quality Assurance Process

Every 5/8" Hitch Pin & Clip undergoes comprehensive testing including dimensional verification, material composition analysis, and surface finish inspection. Our ISO 9001:2015 certified facility ensures consistent quality.

Installation & Safety Guidelines

Proper Installation Steps

Put the pin all the way through the receiver and the ball mount shank until it is completely in place. Use the spring clip that comes with it to secure it through the side hole. Make sure the tow is fully engaged before you start.

Safety Considerations

Check your pin often for damage like wear, rust, or warping. If any damage is found, replace right away. Don't put more weight on your hitch system than it can handle.

Maintenance Tips

Every time you use the pin, especially after being in salt water or off-road, clean it. Use a light lubricant to keep the receiver tube from closing up.
