8mm &5/16"Darren was buying 2 seperate sets, one SAE and one metric. We all know that a 10mm and 3/8" are close and will "sometimes" work either way and also that 13mm and 1/2", 14mm and 9/16" the same but there really is no reason to leave out a common wrench. I can see why lots of sets don't have the 11mm and 16mm wrenches but a 16mm is becoming more of a common wrench as well. When I buy tools I want EVERY wrench size available from the smallest to around at least the 1" or equivelant metric.
11mm &7/16"
14mm &9/16" extremely close
16mm &5/8"
19mm &3/4"
Those are equivalent, the rest you mentioned are off enough you should not be using them for the other size.
I didn't go bigger than 19mm because at that point if you are a little off a little play will still work without rounding off the nut.
I agree if you are buying seperate sets you should have them included, and the sets of Craftsmans I bought before from Sears had all the sizes, and I liked it for that.
It went all the way to 1 1/8"
Now I got me some bigger ones all the way up to 3" from HF, with these sizes HF quality works good enough.
