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?


I've only seen this in combo MM, SAE sets
With the missing MM having the same size in SAE
5/32 is 0.156 inches; 4mm is 0.157 inches
5/16 is 0.313 inches. 8 mm, is 0.315
and The 3/8 wrench is the same as 10 mm.
but 10 mm is very common and is normally included

There is another consideration. Not all tool manufacturers make precise
tools unless they are a specialty tool company. That includes metric or
SAE. One of my 14mm open end wrenches from one company is 14.5mm, and
one from another company is 14.25mm. If you have a pair of inside
calipers, and more than one brand of wrenches, check it yourself.
