Replace a swollen or seized factory nut with this Dorman wheel lug nut, part number 611-143 from the Dorman OE FIX line. It is a one-piece carbon steel nut that takes the place of the original two-piece design. It fits many vehicles, among them the 1979-1993 Ford Mustang, 1984-1994 Ford E-150 Econoline and 1984-1994 Ford E-150 Econoline Club Wagon. See the Buyer's Guide tab for the full list.

On certain vehicles, the original lug nuts are built in two pieces with a thin veneer cover. Repeated use can damage that veneer, and moisture that gets underneath can make the cover bulge. A bulged nut can be difficult or impossible to remove, and freeing a stuck one usually means damaging the wheel itself. This Dorman wheel nut is designed to match the original's fit and function without the separate cover.

  • Improved design: a direct-replacement, one-piece lug nut in place of the two-piece factory design, which often leads to early failure of the wheel nut.
  • Corrosion resistant: the OEM-style veneer is gone, so there is no cover for moisture and rust to get under and deform.
  • Thoroughly tested: put through 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: 1/2-20 thread, dome top, 13/16 in. hex, 2-1/32 in. length.
