You can never have too big a hammer

I'll confess.
There must be a fine distinction between torque setting with a Click torque wrench and angle setting but even as an engineer, I don't really understand it.

To me, if you tighten a bolt you get to a point when it locks. And as TTT says at a relatively low torque. After that, further tightening both increases the torque load and the head angle ??

To me it's a distinction between measurement techniques rather then final result. If anyone can explain why one instead of the other I'd be greatful ??

I'm sure other old farts will remember old style torque wrenches with the separate pointer that swung around a graduated scale as you put load on them.
Graduated in Ft Lbs, measurement in angle.
Aren't these just a variation on the theme ??
