The original lug nuts on certain vehicles have a failure-prone two-piece design that makes warping common and removal difficult. There's often a thin veneer that gets damaged with repeated use, and if moisture gets underneath it can cause the cover to bulge. Those failures can make the nuts difficult or impossible to remove, and if they get stuck, removing them usually requires damaging the wheel itself. This Dorman OE FIX replacement matches the OE fit and function but has a one-piece, carbon steel design to prevent similar issues from happening in the future. Quality engineering - designed in the United States and backed by decades of automotive aftermarket experience Thoroughly tested - part has undergone proof load, salt spray, hardness and thread check testing to meet strict standards Corrosion resistant - by removing the veneer of the OEM lug nut design there's no chance of moisture and rust causing it to bulge and deform Improved design - direct replacement, one-piece lug nut design, vs. two-piece factory design that often leads to premature failure of the wheel nut Package Dimensions: 3.60 x 2.40 x 2.19 inches Package Weight: 1.05 lb Package Quantity: 1 UPC: 019495111382 Color: Chrome Grade Type: Regular Hex Size: 19 mm Material: Steel OE Replacement Or Custom Performance: OE Replacement Open End Design: No Overall Length: 1.378 IN Package Contents: 10 Wheel Lug Nuts SAE or Metric: Metric Seat Style: Radius Thread Diameter: 12 MM Thread Direction: Clockwise (Right) Thread Pitch: 1.5 MM Thread Size: 12 MM Thread Type: Fine Washers Included: No Wheel Lock Key Included: No Wheel Nut Style: Acorn Country of Origin: IN
