When you mount a ball mount on your trailer hitch, you expect it to stay put. Whatever type of load you are hauling, having towing equipment that can work as hard as you do is a must. For all types of heavy-duty towing, CURT 5/8" hitch pins and clips pack a little extra punch. We make our 5/8" hitch pins out of solid steel and coat them in one of four finish options. All of these finishes offer excellent resistance to rust and corrosion for long-lasting, smooth operation. CURT hitch pins are also constructed with a 105-degree bend, creating a useful handle for a better grip and allowing the pin to stay securely engaged in the trailer hitch and ball mount. This particular 5/8" hitch pin features a black zinc finish and comes with a standard retainer hole to accept the included clip. It provides reliable installation for any ball mount or hitch-mounted accessory with a 2" shank, making it the perfect fit for class 3, 4 and 5 trailer hitches.

Bought this to hold on a trailer hitch receiver light. The black finish makes it blend in with the receiver perfectly. Very well made.

Pin is good, color is not a pure black, almost looks as if it was dipped. Size is right on.

Somehow these were not included in a multiple item order or were lost out of the package before it got to my door. But Amazon quickly sent a replacement.

I purchased this product based on the picture showing the drilled hole zero degrees with the handle. What I received has the hole 90 degrees from the handle. This is a complete waste for me and will need to return. Don't very trust product pictures! Made in China 🇨🇳 .

Worked perfectly well with the 2 inch hitch on my SUV. Coated so I suspect it will last as long as the vehicle too!

I love the pin - super solid - very confident in its performance. The clip is also very solid, which has the side effect of being difficult to get on and off. It's probably unnecessarily stiff, but at least I know it's not going anywhere!
