<p>According to a first aspect of the invention we provide an apparatus for reaction-free and reaction-assisted tightening and loosening of an industrial fastener including: a motor to generate a turning force to turn the fastener; a turning force multiplication mechanism for a lower speed/higher torque mode including a plurality of turning force multiplication transmitters; a turning force impaction mechanism for a higher speed/lower torque mode including a plurality of turning force impaction transmitters; a housing operatively connected with at least one multiplication transmitter; a reaction mechanism to transfer a reaction force generated on the housing during the lower speed/higher torque mode to a stationary object; wherein during the lower speed/higher torque mode at least two multiplication transmitters rotate relative to the other; and wherein during the higher speed/lower torque mode at least two multiplication transmitters are unitary to achieve a hammering motion from the impaction mechanism.</p>
