BOLT Receiver Hitch Lock 5/8" for Ford & Lincoln Center-Cut Keys — Stainless Steel, Auto-Return for 2"–2.5" Receivers

The BOLT 7040474 receiver hitch lock secures 5/8" receiver pins and opens with your Ford or Lincoln center-cut ignition key, eliminating extra keys for your trailer hitch.

Designed for truck owners who tow regularly, this BOLT receiver lock replaces a separate hitch key by matching your vehicle's center-cut Ford or Lincoln ignition profile. Built from stainless steel components and engineered locking internals, the lock is intended for Class 3–5 hitches (2"–2.5" receiver) with a 5/8" diameter pin. It includes weather-resistant features and an auto-return mechanism so the lock fastens automatically when you remove the key.

How does this receiver lock work with my Ford or Lincoln key?

The lock is manufactured to accept center-cut Ford and Lincoln ignition keys so you can use the same key that starts your vehicle. Before ordering, verify compatibility by checking your vehicle's year, make and model against the product fitment. Using a single key reduces the chance of losing a separate hitch key and streamlines your keyring.

• Accepts center-cut Ford/Lincoln ignition keys
• No extra hitch key required when vehicle key is compatible
• Check fitment by vehicle year/make/model

Is this lock durable enough for towing and outdoor use?

The 7040474 features a solid stainless steel pin and a stainless steel shutter to resist corrosion and contamination. An automotive-grade lock cylinder and weather-resistant jacket protect the core from moisture and dirt, while a plate tumbler sidebar and double ball bearing mechanism improve resistance to picking and forced entry. BOLT also backs the product with a limited lifetime warranty.

• 5/8" stainless steel pin for Class 3–5 towing
• Stainless steel shutter and weather jacket for corrosion resistance
• Security features: plate tumbler sidebar and double ball bearings

What convenience features should I expect during everyday use?

The lock includes an Auto-Return spring that secures the pin in place automatically when you remove the key, so you don’t have to push the pin closed manually. The lock is sized for 2"–2.5" receivers and installs quickly without complex tools. Because it pairs with your vehicle key, you avoid carrying, tracking, or misplacing an extra hitch key.

• Auto-Return spring locks automatically when key is removed
• Quick install/removal for standard 2"–2.5" receivers
• Simplifies key management by using your vehicle ignition key

How do I choose the right pin diameter for my hitch?

This model uses a 5/8" diameter pin suitable for heavier-duty towing (Class 3–5). If your trailer or accessory requires a smaller pin, BOLT offers other sizes; verify the receiver and hitch class to match pin diameter and load rating. Always confirm that the lock’s pin diameter and receiver opening are compatible before purchase.

• 5/8" pin fits Class 3–5 hitches (heavier towing applications)
• Measure receiver and check hitch class before ordering
• Alternative BOLT models available for smaller pin sizes

Who is this for? The BOLT 7040474 is aimed at Ford and Lincoln owners who tow frequently and want to simplify key management while maintaining a high level of hitch security. It’s particularly useful for truck drivers using Class 3–5 towing setups who need a corrosion-resistant, tamper-resistant lock that integrates with their existing ignition key. Verify your vehicle’s center-cut key type and hitch specifications to ensure the best fit.
