Default Why do they skip sizes of metric combo wrenches?

Be it Sears, HF, HD, etc.

They often go 6,7,8,10,11,12...

Not always in larger sets. But like who would buy an SAE set of any
size

if
it ran from say 3/8 to 3/4 without a 9/16?

When's the last time you really needed a 9mm wrench? In the Ansi/ISO
standard there is only 7,8,10,13,16,18,21,24,and 30
The German (Predominantly) DIN standard has only
7,8,10,11,13,17,19,22,24,27, and 30mm
The Japanese (JIS) standard uses only 7,8,10,11,12,14,17,19,and 22.

Someplace someone has slipped in a 15mm, as it is included in some
metric tool sets - so why would you want a 9 mm wrench. It doesn't
even match up to a fractional size, falling between 3/32" and 23/64"


Ummm, wouldn't that be the exact reason that you'd want a particular
size wrench? Nothing else fits!

There was a farmer who had a dog, And Bingo was his name-O. B-I-N-G-O! B-
I-N-G-O! B-I-N-G-O! ...



But there are no 9mm bolts or nuts. If it is "buggered", you'd
probably go after it with something else. Who would make a bolt that
there were no tools for?
