Replace bulging, hard-to-remove originals with this Dorman wheel lug nut, part number 611-089, a one-piece carbon steel replacement for a failure-prone two-piece lug nut design. It fits many vehicles, among them the 1984-1990 Chevrolet Celebrity, 1982-1988 Chevrolet Monte Carlo and 1982-1987 Chevrolet El Camino. See the "Vehicles it fits" section for the full list and engine details.
Dorman lug nuts in the OE FIX line address a known problem. The original lug nuts on certain vehicles use a two-piece design with a thin veneer that can be damaged with repeated use. If moisture gets underneath, the cover can bulge, which can make the nut difficult or impossible to remove. A stuck nut often means damaging the wheel to get it off. This replacement is built to match the OE fit and function, and its one-piece carbon steel design is intended to keep those failures from happening again.
- Improved design: A direct replacement with a one-piece lug nut design. The two-piece factory design often leads to premature wheel nut failure.
- Corrosion resistant: There is no veneer, so moisture and rust have no cover to get under and cause it to bulge and deform.
- Thoroughly tested: Proof load, salt spray, hardness and thread check testing to meet strict standards.
- Quality engineering: Designed in the United States and backed by decades of automotive aftermarket experience.
Specifications: M12-1.50 thread, flattop style, 19mm hex, 32mm length.
Consider Dorman Autograde lug nuts if an original nut has a swollen or peeling cap, no longer seats a socket properly, or is difficult to remove.
