trailer hitch pin

Most hitch pins are listed as steel or carbon steel; some product listings simply use the generic term “metal.”

Hitch pins and locks commonly fit standard receiver sizes such as 2" and 2-1/2". Some listings also reference a 5/8" pin distance (pin diameter or hole spacing) used by many trailers and accessories.

Common weather- and rust-resistant features include watertight caps and weather seals around keyholes, corrosion-resistant finishes (such as electrophoretic paint), and other protective coatings to keep moisture out of metal parts.

Convenience features shown include one-handed release mechanisms, magnetic quick-connect designs for fast attachment, and keyed locks that are described as easy to operate.

Hitch hardware is secured using removable clips or cotter pins, threaded bolts with nuts, magnetic quick-connect pins, or keyed locks. For anti-theft protection, keyed tubular locks and some threaded/locking bolt designs are used to prevent unauthorized removal.

Pins and locks are shown compatible with towing accessories such as hitch-mounted racks and bike racks, hitch balls and tow ropes, load hitch plates, and tow-behind lawn attachments like rollers, spreaders, sweepers, tillers, utility carts, lawn tractors, and ATVs.

Listings mention solid carbon-steel construction with electrophoretic paint or other protective coatings, weather-resistant seals and watertight caps to keep out moisture, all-weather designs, and features intended to reduce wobble for added stability.

Alternatives shown include removable clips, threaded hitch bolts with nuts, magnetic quick-connect pins (using strong magnets), and keyed tubular locks for a more secure connection.
