It does and for left handed threads. It's push through. 
I'm talking their big one not the 3/8 or 3/4.
I understand what you are saying but most don't know how to use or look after a torque wrench.
Conventional wound/sprung should be stored unloaded (obvious) and never torqued past the click or used to undo, push through accepted but still bad practice.
I was just clearing up your statement, btw I think you mean 1/2"
Yeah 1/2" sorry.
My general rule is airgun/ratchet most stuff off, if not out comes meter long bar then do everything up with a ratchet or airgun on minimum and torque up.
TBH I use a torque wrench nearly on every single job. All get calibrated 3 monthly.
