A multi-functional wrench having an adjustable construction that allows the nut or bolt engaging surfaces of the wrench to be located at different angles or positions relative to a handle in order to allow the wrench to be used in otherwise difficult to reach areas. The wrench optionally includes a secondary handle removably connected to a preferably arcuate, multi-functional wrench body that is, in turn, removably connectable to a desired wrench head which includes a work-engaging fitting. The multi-functional wrench has a body that is archial or curved in shape and includes at least one drive post or ratchet and a plurality of sockets that are useful for many applications. The wrench is particularly useful to manipulate the body of straight stop and angle stop compression valves connectable to plumbing under sinks, behind toilets and inside cabinets, as well as nuts and bolts.

A hand tool may include a head section defining a first grip portion, a handle section and a second grip portion. The head section includes a top jaw and a bottom jaw defining the first grip portion. The handle section includes a top handle and a bottom handle. The top jaw and the bottom handle forming a first unitary piece, and the bottom jaw and the top handle forming a second unitary piece. The first and second unitary pieces are joined at a pivot point. The second grip portion includes a top grip portion provided at the top handle and a bottom grip portion provided at the bottom handle. The top and bottom grip portions substantially face each other. The first grip portion is made of a metallic material and the second grip portion is made of a non-metallic material.

A wrench includes a body having a handle which a first face defined in each of top and bottom thereof. Each of the two first faces has two first recesses defined therein. Each of the first faces has a first block which protrudes beyond the first face corresponding thereto. The handle has a first function head formed on the first end thereof. The first function head is an open wrench head. The first function head has a first protrusion which is connected to the handle and protrudes beyond the first face. The first protrusion has a second curved face formed on the distal end thereof. The handle has a second function head formed on the second end thereof. The second function head is a box-end wrench head.

A hand tool structure includes a main body and a laser body mounted on the main body. The main body is provided with at least one operation end. The laser body is formed on a whole surface or a partial surface of the at least one operation end by a working machine during a laser process. The whole surface or partial surface of the at least one operation end is provided with at least one first friction face formed by the laser process. The at least one first friction face is a rough surface with particles. The at least one first friction face increases a contact friction force between the at least one operation end and the workpiece.

A wrench structure includes a wrench body provided with a handle. The handle has a top and a bottom each provided with two first faces and two first recessed portions. The handle has a center provided with a projection having two second faces protruding from the first faces. The handle is provided with eight ribs. Each of the first recessed portions is defined between two of the ribs. The handle has two sides each provided with two first side faces. The projection has two second side faces protruding from the first side faces. A first guide angle is provided between each of the first side faces and one of the second side faces. The handle has a first end provided with a first rotation portion and a second end provided with a second rotation portion.

A pliers includes a first member having a first head and a first handle, and a second member having a second head and a second handle. Each of the handles includes a recessed grip area bounded by a forward lip and a rear lip. The rear lip has a cross-sectional area not greater than a cross-sectional area of a portion of the handle adjacent the rear lip and opposite the grip area. The pliers also includes a first grip positioned on the grip area of the first handle and a second grip positioned on the grip area of the second handle.

An apparatus includes a tool assembly. The tool assembly includes a tool device configured to securely receive, at least in part, a nut. An angled elbow assembly is configured to be positioned proximate to, and securely integrally extended from, the tool device. A linearly-extended elongated shaft portion is configured to have a first end portion and a second end portion spaced apart from the first end portion. A step-pad assembly includes a first side portion facing the second end portion of the linearly-extended elongated shaft portion. A second side portion is configured to extend from the first side portion. The linearly-extended elongated shaft portion does not extend through the step-pad assembly and out from the second side portion of the step-pad assembly.

This discloses a multifunctional screwdriver comprising a handle and a matching shaft, the matching shaft holds one end of the handle, wherein the matching shaft apart from the handle opens two screwdriver head holes comprising a first screwdriver head hole and a second screwdriver head hole which are provided at the end of the handle, the second screwdriver head hole provided at the bottom of the first screwdriver head hole. In the present patent application, two screwdriver head holes are provided at the end of the matching shaft, the second screwdriver head hole is provided at the bottom of the first screwdriver set head hole, satisfying the use of the screwdriver head in different thickness and length, so that the matching shaft can be matched with two types of screwdriver head, improving the using efficiency of the screwdriver.

A pliers includes a first member having a first head and a first handle. The first handle has an enlarged end portion and a grip area adjacent the enlarged end portion. At least a portion of the grip area has a smaller cross-sectional area than the enlarged end portion to define a rear lip located at an interface between the grip area and the enlarged end portion. The pliers also includes a first grip having a first open end and a second open end. The first grip is positioned on the grip area of the first handle. The first handle extends through the first open end and the second open end such that the rear lip of the first handle retains the second grip on the grip area of the first handle.

Described are fittings, components, and associated tools for use in coupling pipe or tubing. The described fittings generally include a unitary body having an outer surface and an inner lumen forming a void within said unitary body. The lumen is configured to receive threads for mating with the threads of a female sub end of a pipe or tube. The outer surface includes at least one aperture for receiving a tool that can be inserted within said aperture so as to rotate the fitting about an axis that extends through the lumen of the unitary body. The at least one apertures provide a safe and convenient way to tighten and loosen the fitting during the process of coupling pipe or tubing.
