Dorman 611-089 Wheel Lug Nut - Front or Rear

Dorman 611-089 Wheel Lug Nut

Dorman 611-089 is a metric wheel lug nut built with a one-piece carbon steel design to replace failure-prone two-piece originals. It is made for vehicles that use an M12-1.50 thread, a 60-degree conical seat, and a 19 mm hex, with a natural steel finish.

Key Features

• One-piece steel construction helps eliminate the rust and separation issues common with two-piece lug nuts
• Metric M12-1.50 fine thread with clockwise thread direction
• 60-degree conical seat for proper wheel-to-lug interface
• 19 mm hex size for standard service tools
• Natural steel finish and flattop capped nut design
• OE FIX replacement for select Buick, Chevrolet, Oldsmobile, and Pontiac applications

Detailed Description

This Dorman wheel lug nut is engineered as a direct replacement for select GM vehicles that originally used a problematic two-piece lug nut design. By using a one-piece carbon steel construction, Dorman 611-089 addresses the corrosion and serviceability concerns that can develop over time on original hardware. It is a fitment-based replacement for applications such as Buick Century, Buick Regal, Buick Skylark, Chevrolet Celebrity, Chevrolet Monte Carlo, and Pontiac 6000, among others.

This part cross-references AMS Automotive 6412 for the same application.

What It Helps Solve

• Rust buildup on original lug nuts
• Separation or swelling of two-piece lug nut designs
• Difficulty removing damaged wheel hardware during tire service
• Improper wheel retention caused by worn or distorted lug nuts
• Replacement needs for M12-1.50 conical-seat wheel applications

Installation Notes and Tips

Verify the lug nut-to-wheel mating surface before installation to confirm proper seat style and safe fitment. This part uses a clockwise, right-hand thread and a 60-degree conical seat.
