Dorman 611-073 Wheel Lug Nut - Front or Rear

Dorman 611-073 Wheel Lug Nut

Dorman 611-073 is a direct replacement wheel lug nut for select GM vehicles that use a 1/2-20 fine thread and 60-degree conical seat. It replaces the original two-piece style with a one-piece steel design to address common rust and service issues on older wheels.

Key Features

• One-piece steel construction for improved durability
• 1/2-20 SAE fine thread with clockwise thread direction
• 60-degree conical seat for proper wheel mating surface engagement
• Natural finish and dometop nut design
• 13/16 in hex size for standard service tools
• OE FIX replacement for select Chevrolet, GMC, Buick, Oldsmobile, and Pontiac applications

Detailed Description

This Dorman wheel lug nut is built for vehicles that originally used a failure-prone two-piece lug nut design. By switching to a single-piece carbon steel construction, Dorman 611-073 helps reduce the rust-related separation and repair problems commonly seen on aging factory lug nuts. It is a practical OE-style replacement for classic GM trucks and cars, including Chevrolet C10, GMC C1500, Buick LeSabre, and Pontiac Bonneville applications that require a 1/2-20 lug nut with a 60-degree conical seat.

This part cross-references Raybestos Brakes 8915N for the same application.

What It Helps Solve

• Rust buildup on original two-piece lug nuts
• Broken or swollen lug nuts that are difficult to remove
• Wheel service problems caused by damaged threads
• Improper wheel-to-lug nut seating from worn hardware
• Replacement needs on older Chevrolet, GMC, Buick, Oldsmobile, and Pontiac vehicles

Installation Notes and Tips

Verify the wheel mating surface before installation to confirm the 60-degree conical seat matches the wheel. Confirm thread size, thread direction, and hex size before service. Use proper torque specifications for the vehicle and recheck lug torque after wheel installation.

Quality Assurance

Dorman OE FIX replacement hardware is engineered as a one-piece steel solution to address the weaknesses of the original design and support long-term serviceability.
