1/2in Hitch Pin & Clip Zinc

The 1/2in Hitch Pin & Clip Zinc by CURT Manufacturing (MPN 21401) is a critical fastening component designed for securing trailer hitch receivers and tow systems on light-duty and medium-duty vehicles. Whether you're towing a cargo trailer, utility trailer, or boat on a regular basis, this hitch pin serves as the mechanical lock that holds your receiver in place, preventing accidental separation under load. Built as a direct replacement or upgrade for worn or lost pins, this component is essential for anyone who depends on reliable trailer coupling for work, recreation, or commercial hauling applications.

This 1/2 inch diameter pin is manufactured from hardened steel with zinc oxide coating, offering superior corrosion resistance even in wet, salt-laden, or high-humidity environments—critical for trailer systems exposed to road spray and weather. The zinc finish prevents rust and oxidation that can cause binding or seizing, ensuring smooth insertion and removal across multiple seasons of use. The included cotter-style clip (also zinc-coated) locks the pin in place and prevents vibration-induced loosening during towing, a common failure point in undersized or unfinished fasteners. At just 0.32 lbs, the lightweight design does not affect hitch performance while the compact 2.85 x 0.85 x 6 inch profile fits standard 1.25 inch and 2 inch receiver tubes without modification or adapter plates.

Mechanics and fleet operators rely on CURT Manufacturing hitch hardware because OEM pins often corrode or become lost in the field, leaving drivers without a secure coupling solution. Replacement is straightforward: align the pin through the receiver's locking holes, insert fully, and secure the clip over the protruding end—a task that takes seconds but prevents dangerous trailer detachment. This pin is compatible with CURT 1.25 inch and 2 inch Class I, II, and III receivers, making it a universal solution across most truck and SUV tow packages. Stock one in your truck, trailer, or garage equipment for emergency repairs or routine maintenance to keep your towing setup roadworthy and safe.
