A wrench for rotating a hex head fastener has a frame having one or two jaw faces. If the frame has two faces, they form a 60 degree angle between them. A movable jaw has two faces forming an angle of about 120 degrees relative to each other. A guide connected to the frame controls movement of the movable jaw along a line forming an angle of about 40.9 degrees with respect to a position of one of the frame faces.

An adjustable wrench having a first fixed jaw; a handle extending away from the head and having a longitudinal axis; a second jaw selectively positionable with respect to the first jaw; a rotating rod controlling the positioning of said second jaw and comprising two rotating sleeves; one near the head located in the cut out of the handle; one near the rear located in the cut out of the handle; an end knob on the end opposite the gear train operatively coupling said rod to said second jaw; said rod having 3 holes for split drift pins to secure rotating sleeves and end rotating knob; said rod has a smaller diameter at a specified distance from the rod's end to accept a pin. At the rod's end is an end knob. Said sleeves and end knob rotate, at a latitudinal axis (perpendicular) to handle secured by split drift pins or adhesive. Such a wrench may have a p roof torque of at least the minimum level set forth in ASME B107.8 2003 revision.

A wrench with an open-end wrench head that has at least two jaws. Each jaw has at least one internal engaging surface for engaging with a work-piece such as a nut or bolt that has an axis of rotation. Each of the at least one internal engaging surface of each jaw extends in a direction that creates an imaginary line when the wrench is viewed from a side view thereof. The wrench also has a handle extending from the wrench head and elongated in a predetermined direction defining at least one central axis of the handle. And, the wrench also has a ratcheting means that provides ratcheting capability to the wrench head when the handle is twisted back and forth by a user.

An adjustable wrench has a handle assembly and a gripping assembly. The handle assembly includes a rotating handle, a pivot shaft, and a holding handle. The pivot shaft is securely mounted in the rotating handle, and has a right-handed screw thread and a left-handed screw thread. The holding handle is mounted around the pivot shaft. The gripping assembly includes a base, a lower jaw, an upper jaw, and a guiding module. The lower jaw engages with the left-handed screw thread of the pivot shaft. The upper jaw engages with the right-handed screw thread of the pivot shaft. The guiding module is slidably mounted through the base and the lower jaw and is securely connected to the upper jaw. By turning the rotating handle as well as the pivot shaft, the upper jaw and the lower jaw can be quickly moved to a closed state or an open state.

A modular tool with improved tool interface structures may feature an adjustable wrench body (110) with tool modules (120) which fit within the jaws (114, 116) of the head of the tool. The tool body (110) (120) that serve as tools or as attachment for tool components, like tool bits or sockets. The tool features a ratcheting engagement of the jaws (162, 172) with a quick release (117) and spring bias (176) that allows for easy attachment of the modules.

A ratcheting wrench includes a first jaw with a first jaw insert configured to move relative to the first jaw and a first spring configured to bias the first jaw insert in a first direction. The wrench also includes a second jaw with a second jaw insert configured to move relative to the second jaw and a second spring configured to bias the second jaw insert in a second direction opposite the first direction. When the first jaw insert moves relative to the first jaw and the second jaw insert moves relative to the second jaw, a space between the first jaw and the second jaw increases. This allows the jaws of the wrench to slip over corners of a fastener to achieve a ratcheting effect.
