Dorman 611-087 Wheel Lug Nut

Dorman 611-087 Wheel Lug Nut for M12-1.50 Applications

Dorman 611-087 is a metric wheel lug nut built with a one-piece carbon steel construction to replace failure-prone two-piece originals. It addresses common rust and service issues found on select Buick, Chevrolet, Oldsmobile, and Pontiac vehicles with M12-1.50 wheel studs.

Key Features

• One-piece steel construction for improved durability
• Fine-thread M12-1.50 metric design
• 60-degree conical seat for proper wheel mating surface engagement
• 19 mm hex size for standard service tools
• Natural finish with dometop capped nut end type
• Right-hand, clockwise thread direction
• OE FIX replacement for common factory lug nut failures

Detailed Description

This Dorman wheel lug nut is engineered as a direct replacement for select OE lug nuts that use a two-piece design prone to corrosion and difficult removal. The one-piece carbon steel body helps reduce the rust-related separation issues often seen on older factory hardware, while the dometop capped nut profile and 60-degree conical seat support secure wheel mounting. Part number 611-087 is a practical service replacement for vehicles such as the Chevrolet Cavalier, Pontiac Fiero, and Buick Skylark when the original lug nut design has deteriorated.

This part cross-references Remy 92540 for the same application.

What It Helps Solve

• Rust buildup on original two-piece lug nuts
• Broken or swollen lug nut caps that complicate removal
• Worn threads on aging wheel hardware
• Improper wheel-to-lug nut seating from damaged originals
• Service issues on older Buick, Chevrolet, Oldsmobile, and Pontiac wheel assemblies

Installation Notes and Tips

Verify thread size, seat style, and wheel mating surface before installation. This lug nut uses M12-1.50 fine threads, a 19 mm hex, and a 60-degree conical seat. Confirm the wheel design matches the lug nut seat style for safe fitment.
