5/8in HD Hitch Pin

The 5/8in HD Hitch Pin from CURT Manufacturing is the essential fastening component for securing your trailer hitch connection under load. Whether you're towing a utility trailer, boat, or cargo carrier, this pin locks the hitch ball or coupler into the receiver tube with rock-solid reliability. For anyone serious about towing—from weekend haulers to commercial operators—a quality hitch pin isn't optional; it's the last line of safety before your trailer separates from the tow vehicle.

Constructed from hardened steel and finished with zinc plating, this hitch pin delivers corrosion resistance and durability in all weather conditions. The 5/8-inch diameter shaft matches the standard Class II and Class III hitch receiver opening, ensuring a snug fit that resists vibration and movement during transit. The included clip prevents accidental loss, holding the pin firmly in place even on rough terrain or during highway driving. Zinc plating protects against rust and salt spray, extending service life and reducing maintenance in coastal or high-humidity environments.

This pin works with any trailer hitch rated for 5/8-inch pin holes, making it compatible with CURT hitches and most aftermarket receivers on the market. At 0.6 lbs and compact dimensions, it stores easily in a glove compartment or tow kit. Mechanics and fleet operators trust CURT's engineering for consistent performance; replacement pins should be inspected regularly for wear and replaced immediately if the shaft shows bending or the clip loses tension to maintain safe towing operations.
