Abstract (en)
[origin: US4377955A] A wrench having a handle with an actuating lever arm pivoted for operation to rotate a nut engaging ring geometrically configured to accept a nut or bolt head. The nut engaging ring includes two tappets extending in the plane of rotation of the lever arm. A torque applied to the lever arm engages these tappets and thereby causes the nut engaging ring to rotate with increased force.
