WONEHI Trailer Hitch Pin, 5/8-Inch Diameter

For drivers matching a hitch pin to a heavier-duty receiver, the WONEHI has a 5/8-inch diameter and is listed for 2-1/2- or 3-inch receivers. Its bent handle is designed to make the pin easier to grip, while the included clip holds it in place after the holes are aligned. The listing also gives a load rating of up to 21,000 lbs, though that figure should not be mistaken for the towing capacity of your vehicle or hitch.

If you prioritize a beefier steel pin and a grippable handle, this setup fits that approach, if you prefer a keyed lock for theft deterrence, the supplied details don’t establish that feature.

Where it shines

The practical benefit is a straightforward pin-and-clip arrangement for securing a ball mount or another hitch accessory in a compatible receiver. The 105-degree bend gives you a handle to hold while inserting or removing it, which can be handy when working beside a receiver with limited finger room. Solid steel construction and a zinc-plated finish are specified, with the coating intended to resist rust and corrosion from exposure to rain and dust.

The listing describes a 5/8-inch pin hole and shanks in 2-inch or 2-1/2-inch lengths, and names Class 3, 4, or 5 hitches among the intended fits. Those details make matching the pin to your receiver and accessory important, “heavy-duty” alone doesn’t guarantee a fit. The stated rating of up to 21,000 lbs is a rating for the pin as listed, not permission to exceed the limits of the trailer, vehicle, receiver, or other towing components.

What matters most

Start with the receiver and accessory holes: they need to line up, and the pin’s diameter and usable length must suit that combination. During a hookup, for example, you would slide the ball mount into the receiver, align the side holes, pass the pin through, then attach the clip. That’s a simple routine, but a pin that doesn’t seat fully or take its clip securely isn’t a useful match.

Without having tried it, the main buying distinction is clear from the listed design: this is a steel pin with a bent handle and clip, rather than a described keyed security device. The product name includes “lock,” but the details provided don’t specify a key cylinder or theft-deterrent function. You’ll appreciate it if you need a removable pin for a compatible receiver and value the handle for everyday hookup and removal. It may not suit you if your receiver uses a different pin size or you’re shopping specifically for keyed security.

Best use cases

This pin makes the most sense for towing setups where the receiver and ball mount both accept its 5/8-inch diameter and the stated receiver sizes. The coated steel construction is relevant for equipment that may be exposed to outdoor conditions, though no particular cleaning or maintenance routine is provided. Check that the clip can be fitted after insertion and that the pin passes through both sides of the receiver and accessory before towing.

When it makes sense

Choose it when its listed dimensions match your existing hitch hardware and you want a simple pin-and-clip connection with a bent grip. Compared with a basic straight pin, the handle may be easier to grasp during removal, compared with a dedicated locking hitch pin, this listing doesn’t provide enough detail to count on keyed theft protection. The deciding point is fit first, then function: if your setup needs a different diameter, length, or a specified keyed lock, this is not the right detail set to buy against.
