  1. Time is money. If you can halve the labour time (And you can, with power tools) you can theoretically halve the labour cost. On non critical fasteners the torque isn't critical and any experienced mechanic can tell if they are tight enough or not, even if they use the power tool to nip the fasteners and then do the final torque by hand. I have worked as a mechanic for 30 plus years and could count on one hand how many fasteners I have stripped from over tightening. Put it this way: if you work for an employer who pays by the hour, you will always be under the pump to get the job done as fast as possible. And with no comeback.
