About this item

  • ERGONOMIC ACCESS. Instead of a single hole, the grooved head of this trailer pin allows the hitch clip to be inserted at any perpendicular angle. It is easier to use and more ergonomic to install whenever needed
  • VERSATILE. The 1/2-inch diameter of this hitch pin is compatible with any ball mount or other trailer hitch accessories with a 1-1/4-inch shank and 1/2-inch pin hole, making this receiver hitch pin a perfect fit for most class 1 and class 2 hitches
  • EASY TO GRIP. The 105-degree bend in this trailer hitch pin creates a useful handle for easier use and allows the pin to stay securely engaged in the trailer hitch and ball mount
  • CORROSION-RESISTANT. Protected by a durable zinc-plated finish, this tow hitch pin maintains excellent resistance to rust and corrosion for longevity and hassle-free use every time
  • HIGH-STRENGTH. This 1/2-inch trailer hitch pin is made out of solid steel for reliable strength, safety on the road and confidence with every mile of your adventure


The job of a hitch pin is incredibly important in towing, and for this reason, CURT hitch pins and clips are made to be of the utmost quality, providing you with reliable security for your trailer and cargo. CURT 1/2" hitch pins measure a full half inch in diameter and are constructed from solid steel. This helps ensure they have the strength they need to serve your towing needs. Our 1/2" pins are available in a number of finishes to give you options for your specific vehicle and trailer hitch. This 1/2" hitch pin features a zinc finish and comes with a groove that allows the clip to be inserted at any angle. All CURT 1/2" pins come with a 105-degree bend, making them easier to handle and operate when mounting your ball mount. 1/2" hitch pins will fit any CURT ball mount or hitch-mounted accessory with a 1-1/4" shank.

It worked great for my 1-1/4" extension. It was long enough to receive the retainer clip just fine. I don't know why others said it was not. I was also impressed with the cheap price for such a quality piece of hardware and would not hesitate to buy another one again if the need ever arises.

Serves my purpose, but item is not to spec.Product page photo has square end, diagram shows conical end. Item is square end. Actual length is 3 11/16". Distance from inside to center of groove is 2 3/8" not 2". Diameter is correct at 1/2".Works for me, but specs are specs. So, its 4Stars.

It holds my hitch in place. The keeper pin seems hard to get it place. Otherwise, good enough.
