Dorman Wheel Lock Set M14-1.50, Keyed Locking Lug Nuts, Corrosion-Resistant

The Dorman 712-681 M14-1.50 Wheel Lock Set is a precision-made locking lug kit that replaces factory wheel nuts to deter theft while delivering corrosion-resistant durability.

Designed for drivers who want a straightforward way to protect their wheels, this wheel lock set fits M14-1.50 threaded hubs and is manufactured to consistent specifications for long service life. Each kit undergoes fitment checks and corrosion resistance testing so the pieces perform reliably on the vehicle. Because Dorman offers multiple configurations, confirm thread size, quantity, and finish before purchasing to ensure proper fit and appearance.

What exactly does this wheel lock set protect against and how does it work?

The kit replaces one or more factory lug nuts with specially keyed locking nuts that require a matching key to remove. That extra step prevents casual or opportunistic theft by making wheel removal more difficult without the unique key. It’s a mechanical deterrent intended to slow or stop theft attempts rather than a theft-proof guarantee.

• Replaces standard lug nuts with keyed locking nuts
• Requires a matching key socket for removal
• Acts as a visible and physical deterrent to wheel theft
• Not a substitute for other security measures (parking, cameras, alarms)

How do I confirm fitment for my car or truck?

This specific set is sized M14-1.50, so you need to match that thread pitch and diameter to your vehicle’s wheel studs. Dorman publishes the product attributes—check stud thread size, seat type, and the number of locking nuts included. If in doubt, compare the new part’s measurements to one of your existing lug nuts or consult your vehicle’s owner manual.

• Thread size: M14-1.50 (confirm with existing lug nuts)
• Check seat style and wheel compatibility before buying
• Available in different quantities and finishes—select the correct kit
• Use included key socket; ensure you store the key securely

What materials and tests support long-term reliability?

Dorman builds the locking nuts from quality materials and produces them to strict specifications to maintain consistent performance. The components go through try-on fitment and corrosion resistance testing to reduce the risk of early failure in real-world conditions. These steps help ensure the parts remain serviceable across seasons and driving environments.

• Constructed from durable, corrosion-resistant materials
• Undergoes fitment checks for correct seating and threading
• Corrosion resistance testing for longer service life
• Manufactured to repeatable quality standards

How do I install and maintain these locking lug nuts?

Installation follows the same basic procedures as replacing standard lug nuts: thread by hand to avoid cross-threading, then torque to your vehicle manufacturer’s specification using the supplied key socket. Periodically check tightness and inspect for corrosion; apply anti-seize sparingly if recommended for your vehicle. Keep the removal key in a safe, accessible place so you can service tires or change wheels when needed.

• Hand-start threads, then torque to OEM spec with the key socket
• Inspect periodically for corrosion or damage
• Store removal key where you can access it for tire service
• Follow vehicle manufacturer torque recommendations
