A wrench, connectable to a standard square shaped extension, has a wrench head with opposed jaw faces which together define a plane that lies perpendicular to the respective jaw faces. A standard square shaped extension socket is affixed to the wrench head, where a standard square shaped extension can be inserted into the standard extension socket, along a direction that is non-orthogonal to the transverse plane. The standard extension socket can be attached to a frame of the wrench head, or to a rotatable guide which controls movement the opposed jaw face which is movable.

A clamping connector for an autofeed attachment for a screwdriver tool. The connector has a cam action lever that actuates a clamp. The lever moves between an open position and a closed position. In the closed position, the clamp slightly deforms to hold the autofeed attachment onto an extension pole and/or the front end of a screwdriver tool (or electric drill). The connector, while either in its ‘clamped’ or ‘open’ state, includes an open central region that allows a rotatable shaft or drive bit to pass therethrough, unimpeded. The connector includes a washer with a flat portion that prevents improper axial rotation of the lever as the lever is actuated, or at any stable position. The flat extension helps guide the lever into pivoting along a longitudinal axis of the attachment. An adjustable bolt adjusts the clamping force, and secures the lever, washer, and clamp together on the autofeed attachment.

A rotary impact tool includes a housing, an electric motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece of at least 900 ft-lbs of fastening torque. An anvil has a bore defining a hexagonal cross-sectional shape and having a nominal width of 7/16 inches. A hammer is rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil. A spring biases the hammer in an axial direction toward the anvil. A battery pack has a nominal voltage of at least 18 Volts and a nominal capacity of at least 5 Ah. The rotary impact tool has an overall weight including the battery pack that is less than or equal to 7.5 pounds. A ratio of the fastening torque to the overall weight is greater than or equal to 120 ft-lbs per pound.

A fastener driving tool is provided for driving a fastener onto a threaded rod. The fastener driving tool includes a housing, and an input shaft rotatably supported by the housing. The input shaft defines a first rotational axis. An output member is rotatably supported by the housing. The output member is configured to rotatably support the fastener. The output member is configured to receive the fastener and a portion of the threaded rod. A transmission assembly is operatively coupled between the input shaft and the output member. The transmission assembly is configured to convert an input torque from the input shaft about the first rotational axis to an output torque about a second rotational axis acting on the output member. The second rotational axis is disposed at an angle relative to the first rotational axis.

An engagement part of a tool such as a hydraulic wrench (10), the engagement part (1) such as a ratchet link being arranged to engage a workpiece and a power head (11), the engagement part (1) being arranged to convert movement generated by the power head (11) into movement of the workpiece, the engagement part (1) comprising a mounting for the power head (4, 14), the mounting (4, 14) comprising a moveable portion moveable (4) from a first position where the power head (11) is fixed relative to the engagement part (1) and a second position where the power head (11) can move relative to the engagement part (1), the moveable portion (4) comprising a pin having a length and slidable along its length in a bore (17) in the engagement part (1) and a friction lock (2, 3) comprising a compressible member (3) and a compressing member (2) arranged to compress the compressible member (3), the compressible member (3) being arranged such that it expands in at least one extent on compression by the compressing member (2) such that in a locked position of the friction lock the compressible member (3) extends so as contact the pin (4) so as to restrict movement of the pin (4).

A structure for mounting a cover plate in a head portion of a wrench is disclosed. An end surface of the head portion is concavely provided with a receiving chamber. The head portion is also concavely provided with a recess at the opening of the receiving chamber. The cover plate is mounted in the recess to close the receiving chamber, and the cover plate is fixed in the recess by the peripheral wall of the recess itself In other words, the cover plate is mounted in the head portion of the wrench without using any connecting element and is fixed by the head portion of the wrench itself. The cover plate, once fixed, is kept from coming off so that the components mounted in the receiving chamber of the head portion will not fall out.

A torque tool includes multiple bits, a handle, a pointer and a scale ring. Each of the bits includes a colored area. In use, the handle is connected to a selected one of the bits. The handle is operable to set multiple maximum values of torque transferable to the bit from the handle corresponding to the colored areas of the bits. The pointer is formed on the handle. The scale ring includes multiple colored areas corresponding to the colored areas of the bits. The scale ring is rotated around the handle as the handle is operated to set the maximum values of torque, thereby aligning the pointer with one of the colored areas of the scale ring corresponding to the colored area of a selected one of the bits.

A multi-function tool. The multi-function tool includes a first socket body having a first sidewall defining a first socket and a second socket, the first socket body being aligned with a first axis. The multi-function tool also includes a second socket body having a second sidewall defining a third socket, the second socket body being aligned with a second axis that is substantially parallel to the first axis. The first socket body is connected to the second socket body by a bridge.

The present disclosure provides a tool comprising a centrally placed tool head disposed between first and second handle portions which a user may grip with either hand in order to comfortable apply torque about the central toolhead from either side in a safe manner. The ability to effectively utilize force from both arms without losing balance facilitates a greater application of torque. The tool may be a wrench of any type utilizing a central wrench head of any type, but may also be another type of leverage-based tool such as a screwdriver or hammered tool.

A hand tool including a control element for receiving one or more finger digits of a user. The control element is positioned on the body component and may be in the form of an aperture defined by a perimeter surface. A user places one or more fingers within the control element and applies pressure to rotate the body component.
