Okay, I'm not the sharpest knife in the drawer & I admit it.
What exactly am I looking at on that linked page? Where do I go to read up on this stuff & learn something new(to me anyway

). Is that what you use if you must put an extension on the T/Q wrench to get on the fastener? I'm taking that "drawing" too literally, right? The drawing of the open end wrench is a representation for the extension you are putting between the socket & the T/Q wrenches head?
That tool pictured looks kind of like the "rotational T/Q measuring tool" I have from snap on in my "industrial section" in the lower box. So I know I'm not getting this for sure. TIA!
