A universal ratcheting tool provides improved handling of tools that are difficult to use on their own, specifically, hexagonal wrenches. The universal ratcheting tool includes a handle and a body with a ratcheting mechanism within the handle. The body includes a first aperture for receiving a tool, and the first aperture includes slots to accept a plurality of sizes of tools. The body also includes a second aperture where the tool extends out of the body. A retaining component is coupled with the body to retain the tool and a retaining tab is able to be used to open and close the retaining component. Once the tool is positioned and retained within the universal ratcheting tool, a user is able to easily install or remove an object such as a screw with the benefit of a comfortable handle and the ease of use of the ratcheting mechanism.

A fastener extraction device includes a body configured for attachment to a power driver tool, and allows a rotating chuck provided thereby to extend therethrough. The extraction device includes a plurality of spring-biased grasping arms that are pivotably attached to the body and are moved between opened and closed positions by a actuation collar that is in operative engagement with the grasping arms. When the grasping arms are moved to a closed position, the extraction guides form an extraction aperture around the shank of the fastener below its head, allowing the operator to pull on the fastener using the leverage of the power driver tool to extract it from a surface in which it is embedded. Once the fastener is extracted, the actuation collar is rotated, so as to allow the grasping arms to move to an open position, whereupon the extraction guides release the fastener.

A power tool has a housing, an output member coupled to the housing, and a motor, rotational motion sensor, timer, and control circuit in the housing. The timer is initiated, and the rotational motion sensor monitors rotational motion of the housing about an axis. The control circuit determines the direction of the rotational motion of the housing, whether the direction is different from a previous direction of rotational motion of the housing, and whether a value for the timer exceeds a predetermined threshold. If the direction is different from the previous direction and the timer value is less than the predetermined threshold, the control circuit initiates a protective action for the power tool. The control circuit also drives the motor to cause the output member to rotate in a direction that corresponds to the detected rotational motion of the housing. 1.

A torque multiplier apparatus includes an input pinion, a geared torque multiplier mechanism, and an input retainer. The input pinion and the input retainer include first and second identical connectors so that a detent stud can be positioned in either one of the first and second connectors, allowing the torque multiplier to be used for increased torque (and reduced speed) or for increased speed (and lesser torque). A related method includes engaging the driving tool with the first connector and the socket with the second connector to provide an increased torque on a socket to break loose a fastener, and flipping the torque multiplier so that the driving tool engages the second connector and the socket engages the first connector to provide an increased speed of torsional rotation to more quickly remove the fastener from the shaft. The detent stud is torsionally shearable, thus preventing over-stressing and damaging the tool. 1. A method comprising steps of:providing a torque multiplier tool with first and second identical input/output connectors operatively connected by a torque multiplying mechanism, a driving tool, and a socket;engaging the driving tool with the first connector and the socket with the second connector;engaging the socket on a fastener and operating the driving tool to provide an increased torque on the socket to break loose the fastener from a tight position;flipping the torque multiplier tool so that the driving tool engages the second connector and the socket engages the first connector; andoperating the driving tool to provide an increased speed of torsional rotation to run the fastener along a fastener-engaged shaft to more quickly remove the fastener from the shaft.2.

A fastener tool assembly for installing breakaway torque nuts includes a socket having a first end attachable to a driver of a fastening tool. A second end of the socket operably engages a detachable wrenching ring of a breakaway torque nut. A window is formed in a sidewall of the socket, sized and configured to permit at least one wrenching ring to pass therethrough. A catch permits insertion of the wrenching ring into the socket, but prevents the detached wrenching ring from freely falling out of the open end of the socket. A sleeve associated with the window selectively permits passage of one or more detached wrenching rings through the window, or prevents passage of the detached wrenching rings therethrough.
