Hitch Locking Pin (3.5in x 5/8in)

The Hitch Locking Pin by WEIGH SAFE is a heavy-duty security fastener engineered to prevent trailer hitch coupler theft and accidental disconnect during transport. Measuring 3.5 inches in length with a 5/8-inch outer diameter, this locking pin is essential equipment for any vehicle owner towing valuable cargo, boat trailers, or equipment haulers. Whether you're a weekend enthusiast hauling a utility trailer or a fleet operator managing multiple towing vehicles, a quality hitch locking pin provides the mechanical assurance that your trailer remains securely coupled under all road conditions.

Manufactured from solid steel with a zinc oxide finish, this hitch locking pin offers corrosion resistance and durability in harsh weather environments. The zinc oxide coating protects against rust and salt spray exposure, critical for vehicles operated in coastal regions or winter climates where road salt accelerates oxidation. The 5/8-inch diameter shaft provides a secure fit in standard hitch receiver openings, while the 3.5-inch length ensures full engagement with the coupler locking mechanism. This precision-engineered pin's robust construction means it will not bend, warp, or fail under the vibration and stress loads encountered during highway towing, making it a trusted component in the WEIGH SAFE product line known for reliability and engineering precision.

This hitch locking pin is compatible with standard 2-inch and 2.5-inch Class III and Class IV hitch receivers found on pickup trucks, SUVs, and commercial vehicles. Installation requires no special tools—simply insert the pin through the receiver holes and coupler until fully seated, then secure with a padlock or chain for maximum security. Mechanics and fleet managers rely on WEIGH SAFE hitch pins for their straightforward installation and fail-safe operation in everyday towing applications.
