Ford: 1/2 - 20 x 1 1/2

Stainless Steel Cover

Troublesome lugnut on older vehicles. Rust develops in between the steel lugnut and the chrome cover after several years. The lugnut becomes oversized due to rust-jacking and gets stuck in socket when attempting to remove lugnut. Then have to use pliers to get lugnut out of the socket, and are left with unattractive brown rusty lugnut without the chrome cover.

These truck lugnuts are similar to the 6W7Z-1012-CA passenger car lugnuts listed above but they are a little longer and you use a 3/4" socket wrench to remove the nuts instead of a 13/16" socket wrench. You can use these on a crownvic, but you'll want to replace all 20 lugnuts on the car so that you have the same size lugnut on each wheel. Having to use different sized socket wrenches on different lugnuts is likely to result in damaged lugnuts, damaged socket wrenches, and the tire service shop employees muttering numerous curse words about your car.
