Great fit on a 2003 Ford F-250 super duty
This unique thread pitch and size was hard to find locally. These fit great on the front end of my F250 that sustained damage in a theft.

washers are huge
correct thread size for my chevy but giant washers prevented me from using on many dash bolt holes.. didnt work on vents and some center console places.
