A metered torque wrench for applying a measured torque to a shaft including an elongated housing enclosing a spring being a stack of resilient metal strips. One end of the stack is secured to one end of the housing. The other end of the stack is secured to a coupler journalled into another end of the housing. A dial plate has a scale and is mounted on the coupler adjacent the another end of the housing. When torque is applied by turning the housing with coupler mounted on the shaft, the magnitude of torque is indicated by displacement of a marker on the edge of the housing relatie to the origin of the dial scale. A floating ring retains the torque reading after the torque has been removed.
