"14mm might be too big for the amount of torque that 1/4" can handle"
If this is true, you are certainly working on different kinds of things than me.

I experimented with my Bosch 14.4v Impactor (1/4" hex drive) and a
13/16" (metric equiv: 21mm) socket and successfully removed my F-150
wheel. That's 90 foot pounds of torque to install, usually up to
120ft/lb to remove. I'd say that 1/4" can handle a 14mm socket's
demands, although I did put a twist in an HF 1/4hex-3/8square adaptor
once building a porch. Those 1/2"x8" galv bolts going into 1902 wood
beams under the house were tough, even though I drilled pilot holes.
That took the larger of my drills to accomplish, but I got the holes
drilled and the ledger board installed properly with the impactor. The
adaptor twisted about 20-degrees from the repeated hammering. Wow!
That is an IMPACT load, not a steady torque. Take your torque wrench
and a few adapters, and adapt down to 1/4 drive and try torquing the
wheel nut to 95 ft lbs.

The "generally accepted safe load" on a 1/4" drive is 300 inch lbs -
which comes out to about 25 ft lbs.

Are you possibly confusing bolt torque with tool capacity? That
sounds more like thread limits than tool limits to me.

The actual tested loading is probably 9x your GASL. For manual tool
use, I generally use the tool I know will not break for that use. When
I feel an extension flex, I move up to the next size. It seldom
happens, but why take the chance? Breaker bars are pretty much the
only tool I use which will be pushed into that flex mode. If I know
something is tight but easy to move once it's broken free, I might
take both 1/4" and 1/2" drive sets to the task. I'll break 'em all
free with the 1/2" ratchet/breaker and spin 'em off with the 1/4"
ratchet, spinner, or 3/8" air ratchet/butterfly.


Snappy has a 9 inch 1/4 drive ratchet that is apparently good for up
to 90 ft lbs. That will put a LOT of twist into a 10 inch 1/4 drive
extention!!!!

And I bet it would give a good lifetime, too.
