ABSTRACT:
A torque to yield indicator and method. An indicator and dial members are coaxially mounted relative to the shank of a torque wrench. One corotates with the shank; the other is freewheeling. After the specified torque load is applied to a fastener, the freely rotatable member is held against movement. When the torque wrench is further rotated, the dial and scale on the members show the amount of relative angular movement which is stopped when the preselected amount of rotation has occurred.
