Beyond the CW issue, metric washers fit as designed, SAE washers basically don't. Quarter inch is far too big to give the design function given by 6mm, 5/16" is pretty close to 8mm, and there's nothing close to 7, 10, and 12mm. Why sacrifice function when the correct pieces are readily available. Besides, ours is the only country still using SAE hardware, and that has left the automotive sector big time. The Cap'n
Hmm, 6mm = .2362inches, 1/4 = 0.25 for a grand total difference of .01378. I'll agree on a difference there, but you and I will have to agree to disagree on the "far too big". On the 8mm's (seems to be the most popular thread size on the car) the washer's are nearly identical (which you note) as 8mm = 0.31496 (the diff between a 5/16 washer and a 8mm is, ahem, 0.00246inches - a figure that may indeed be important when measuring deck height but washer size?).
Unless every screw & bolt is getting torqued to exactly the factory specs during reassembly, I doubt the original "desigh function" is being mimicked, regardless of washer size.
Availability is relative - California guys have it different than most of the rest of us.

Then provide me some insight on how you tell which side of the washer is the exposed front side? <grin>
I believe you get the joke.
