i know this is an old thread but new and good information for me. I’m glad we all have different callings in life because as I was trying to figure out my lug size, it never occurred to me to use my calipers which look exactly like this pair! 🤦🏻♂️

The wheel studs are 14 x 1.5 mm. Just because some SAE sockets are close enough in size to "fit" doesn't mean it is an SAE nut.
Ford, GM and Chrysler partnered to document and define metrification of US automotive manufacturing decades ago. This included not only fasteners but most everything required to build automobiles as well.

(from Wikipedia; emphasis mine)
"The Metric Conversion Act of 1975 is an Act of Congress that was signed into law by U.S. President Gerald Ford on December 23, 1975. It declared the metric system "the preferred system of weights and measures for United States trade and commerce", but permitted the use of United States customary units in all activities."
