For all types of heavy-duty towing, the CURT 5/8″ Hitch Pin packs a little extra punch. The 5/8″ Hitch Pin is made of solid steel with a zinc finish for excellent resistance to rust and corrosion for long-lasting, smooth operation. The CURT Hitch Pin also has a 105° bend, creating a useful handle for a better grip and allowing the pin to stay securely engaged in the trailer hitch and ball mount.
This 5/8″ hitch pin features a zinc finish and comes with a swivel-type retainer. Instead of using a detachable clip as a retainer, the swivel pin features a metal tab mounted on a hinge on the end of the pin. When the pin is inserted into the receiver tube, the tab can be flipped sideways to keep the pin in place, and when you want to remove it, the tab can be rotated again to allow the pin to easily slide out. Operation is quick and easy, and there is no risk of losing the retainer clip. This 5/8″ pin provides reliable installation for any ball mount or hitch-mounted accessory with a 2″ shank, making it the perfect fit for class 3, 4, and 5 trailer hitches.
• 5/8″ diameter pin fits 2″ x 2″ receiver tubes
• Quickly secures ball mounts and other receiver tube inserts with no clip needed
• Permanently attached swivel clip cannot be lost
• Bent handle for an easier grip
• Protected by a durable chrome-plated finish
NOTES: Before towing, be sure the hitch pin is in place and securely fastened. Never exceed the lowest weight capacity of any towing component.
