An engine-powered torque wrench (18) has a loop handle (19) that is orthogonal to a torque rod (22) of a torque handle. The engine-powered torque wrench has a heat engine (1) which rotates a toolhead (14) to which selected tools (25) or a striker gear (16) which can hold the selected tools is attachable. The loop handle is adapted to be hand-grasped by a first hand of a user for primary support of a system weight of the engine-powered torque wrench while selectively positioning a selected tool on a targeted item (23) which typically but not necessarily includes a fastener head (24). The torque handle is adapted to be hand-grasped by a second hand of the user for secondary support of the system weight while simultaneously using the second hand for assisting in positioning of the selected tool, leveraging against rotational moment of the tool heat engine and throttling heat engines which are not preset-throttled. The engine-powered torque wrench can be adapted for either right-handed or left-handed use and for either right-side access or left-side access to the targeted item.
