Some click-type torque wrenches have a lower limit of 50 ft-lbs, anything below this is considered hand tightened.

The closest anything has ever gotten to the speed of light (that isn't light, obvs) is the "Oh my god" particle or OMG particle (scientists aren't very creative with naming). It travels at 0.99999999999999999999999 times the speed of light.
