bottom brackets do have a torque setting though no? Seem to think something like 55Nm (or is that something else?) so loads. Loads more than I’d ever crank up with a BB tool so never bother
For crankarms, stems, brake *calipers, etc I’d reccomend what I have, the BBB one for about £50 or so. Came with a decent selection of bits that have yet to show any sign of rounding at all, goes down to 2Nm and the box is quite useful
*brake and gear levers I can’t see the point of torquing, nor doing tight. I do them just nipped enough that they won’t move when operating, that way when I crash they spin around instead of being the taking the brunt of it. Plus I can tweak them pootling along flat stuff
