I thought they are adjustable so you can adjust speed or rpm to suit different applications.

You can adjust speed & level of impact, but not torque setting. Only way to avoid risk of overtightening is to use the rattle gun to undo the nuts & spin them off & to spin them back on lightly & finish off with a wheel brace or torque wrench.

I suppose that with practice & familiarity with a cordless rattle gun it may be possible to get the torque of the wheel nuts in the good enough/ballpark, but the risk of stretching/breaking studs is high whilst gaining that familiarity & how many of us do it regularly enough to have the confidence we are getting it right each time. Bottom line is that cordless rattle guns are still no good for doing up, only undoing

The torque sticks apparently work fairly well with air rattle guns because their impact rate is lower.
