When I bought my wrench sets, they came with all of the SAE sizes but 11/32, and the metric ones had all of those sizes except 23 mm. I've been working on my old Ford truck and old Ford tractor in recent months, and have used the 11/32, 5/8, 11/16, 13/16, 7/8, 15/16, and 1-1/16. Must be a Ford thing. Of course, a true shade-tree just uses an adjustable wrench and vise grips.
Ford uses some weird stuff on tractors, such as the 5/8-18 X 6-1/4" carriage bolts to hold the rear fenders and stabilizer brackets to the axle. Ever try to find a fine thread carriage bolt? And why would you? Surprisingly hard to reach, and rusted out so they spun in the square hole. Had to cut them with a grinder to remove. Tractor parts houses sell new ones, but they're mighty proud of them.
