Over torqueing providing your still within the bolt yield strength will not be a problem but once taken beyond that point a bolt will not recover . Hence good practice to fit new bolts on bolts that have come loose
Torque figures given are to get the bolt into its yield strength with adequate tightness, but not beyond , rendering the bolt reusable without deformation .
