The invention regards a tool (1) for applying torque to an maneuvered object, such as for example a screw head or nut, including at least a first jaw (4), and at least a second jaw (5) where the first jaw (4) and the second jaw (5) are connected to at least one lever (arm) (2). What is unique with the tool is that at least one of the jaws (4, 5) includes at least one recess (7) with a first contact surface (8) and a second contact surface (9) of which at least one of the contact surfaces (8) and (9) is arch-shaped. A method of using the tool is also disclosed.

An open-end wrench includes a stationary jaw including an inclined hole, a through hole adjacent to a first end of an interior surface and communicating with the inclined hole, and a forward hook; a handle pivotably secured to a rear end of the stationary jaw; and a moveable jaw including a forward hook; a hollow cylinder extending from a rear portion to dispose in the inclined hole, the hollow cylinder having an elongated slot on a surface and communicating with an interior of the hollow cylinder, and internal threads at an open end of the hollow cylinder; a biasing member disposed in the hollow cylinder, a threaded fastener secured to the internal threads to urge against a first end of the biasing member; and a pin inserted through the through hole and the elongated slot to stop at a second end of the biasing member.

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 pipe wrench with an extendible handle is provided. The extendible handle may include a web and a flange to reduce bending stress. The pipe wrench may include a locking button that slides within a channel of the web to lock the extension handle at predetermined extended or retracted lengths. The locking button selectively enables the extension or retraction of the extension handle relative to the first handle of the pipe wrench. The locking button is biased by a spring and coupled to the extension handle with an e-clip. The body, the first handle, and/or the extension handle can include composite materials. In some embodiments, carbon fiber reinforced plastics, fiberglass reinforced plastics, and/or other reinforced polymers are used to form one or more features of the pipe wrench.

According to one aspect, a fluid control system is provided comprising a servicing tool set and at least one valve assembly comprising an actuator and a valve operationally engageable therewith; each valve comprising a valve body; each actuator comprising an actuator body having an upper base and side walls; wherein each actuator body is engageable with a valve body, and wherein the system is configured to allow: engaging the servicing tool set with an actuator and subsequently applying torque to an actuator body engaged with a valve body and thereby disengaging the actuator body from the valve body; the at least one valve assembly comprising at least one Normally Closed (NC) valve; wherein the NC valve is configured to allow activating an actuator engaged therewith with pressurized fluid and thereby opening the NC valve, wherein the actuator comprises a nipple and the servicing tool set comprises a ratchet and at least one socket engageable with the actuator body, and wherein the at least one socket is sized and shaped to accommodate the nipple, and wherein the servicing tool set is further configured to allow operationally coupling the pressurized fluid to the actuator.

A removal tool is provided. The removal tool includes a wrench apparatus having a body having a handle, wherein a portion of the body is structured to engage a securing member. The removal tool also includes a locking tool assembly and a transfer assembly. The locking tool assembly has a first jaw, a second jaw coupled to the first jaw, and a handle extending from the first jaw, the first and second jaws being structured to engage a conduit. The conduit is coupled to the securing member. The transfer assembly is coupled to the handles of the wrench apparatus and the locking tool assembly in order to transfer a force therebetween, thereby allowing the securing member to be removed from the conduit.
