Detailed Description

Dorman 712-545MXL is a metric wheel lug nut designed around common Ford truck and SUV wheel hardware requirements. It uses a medium carbon steel body, coarse M14-2.0 threads, and a 60-degree conical seat to match the specified wheel interface on confirmed applications. The vacuum nickel plated surface helps resist scratching and corrosion, making it a practical choice for daily-driven vehicles that see changing road conditions. This part number, 712-545MXL, is a direct fit option for select Ford F-150, Ford Expedition, Lincoln Navigator, and Lincoln Mark LT models when the wheel mating surface matches the lug nut seat style.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Worn, damaged, or corroded wheel lug nuts
• Loose or inconsistent wheel fastening caused by incorrect thread or seat style
• Cosmetic mismatch on factory-style or custom wheels
• Surface rust and finish breakdown on exposed wheel hardware

Installation Notes and Tips

• Verify M14-2.0 thread size, 60-degree conical seat, and wheel mating surface before installation.
