Disclosed is a low reaction oscillating mass-based torquing tool wherein an oscillating mass is excited into near resonant oscillation by reversing pulses resulting in increased energy stored in oscillation about a dual stiffness spring which develops a higher torque output with the stiffer spring action in the tightening direction and hence tightens the fastener.

[ What is claimed is:] [1.] A resonant oscillating mass-based torquing tool comprising:a rotatable resonant oscillating mass;a means for effecting oscillation of said mass;a dual stiffness spring connecting said oscillating mass to a rotating friction set workpiece; and said dual stiffness spring effects a higher torsional output to said workpiece in one tightening rotational direction to rotate said workpiece in a tightening direction; anda lower torsional output in an opposite rotational direction being insufficient to effect rotation of said workpiece in said opposite rotational direction.
