A tool adapted to be driven rapidly includes a driving portion which has a first jaw and a second jaw and an opening between the first and the second jaws configured to receive an object to be driven. The first and the second jaws have first and second engaging sides configured to grip the object to be driven. The opening has a closed end, an open end, and two opposite sides respectively delimited by the first and the second engaging sides. The first engaging side extends along a linear line. The second engaging side extends along a curved line. The closed end of the opening has a smaller width than the open end of the opening.

A wrench includes a body having a head and a handle portion defining a longitudinal axis. The wrench includes a first jaw coupled to the head with the first jaw including first teeth and an edge. The edge defines a width of the first jaw. The wrench includes a second jaw extending through an aperture of the head with the second jaw including a threaded portion and second teeth. The wrench includes an actuator coupled to the threaded portion of the second jaw such that rotation of the actuator relative to the second jaw moves the second teeth relative to the first teeth. A length is measured from the edge of the first jaw to the second end of the handle portion parallel to the longitudinal axis. A ratio of the width of the first jaw over the length is less than 0.06.

A fixed adjustable wrench. The fixed adjustable wrench includes a handle having a fixed jaw and an adjustable jaw forming a gap therebetween. The adjustable jaw is slidable along a shoulder and is adapted to cooperate with the fixed jaw to secure an object within the gap. An engagement member having a first set of teeth is configured to selectively interlock with a second set of teeth of the adjustable jaw. A second end of the engagement member is operably connected to a lever that is selectively moveable between an engagement position and a disengagement position. In the engagement position, the engagement member is coupled to the adjustable jaw via an interlocking of the first set of teeth and the second set of teeth. In the disengagement position, the engagement member is disengaged from the adjustable jaw allowing selective positioning of the adjustable jaw.

The present disclosure is directed to an apparatus for use with an adjustable wrench to limit the displacement of a broken portion of the adjustable wrench relative to the remaining parts of the adjustable wrench when the wrench fractures.

An adjustable dual-range wrench including an elongate handle and a fixed jaw carried by the handle. The fixed jaw includes multiple teeth disposed linearly along the jaw. A hook jaw is pivotably coupled to the handle opposite the fixed jaw. A toothed lobe is adjustably positioned along the fixed jaw between an outer engagement region sized to engage a first range of sizes and an inner engagement region sized to engage a second range of sizes. The hook jaw comprises a first set of teeth associated with the outer engagement region and a second set of teeth associated with the inner engagement region.

Disclosed herein are devices, systems, and methods of an adjustable crowfoot wrench for use with large format fasteners such as bolts or hydraulic line nuts over 1 inch in size. The adjustable crowfoot wrench includes a base, a translating arm, and a gear. The translating arm include one or more fastener pads and a threaded translating shaft. The gear is configured to threadably engage the threaded translating shaft of the translating arm. The threaded translating shaft is configured to be received by and translate through a translating channel of the base. The base also includes a stationary pad, a drive aperture and gear retaining arms. The gear is retained by the gear retaining arms of the base when the gear is threadably engaged with the translating arm within the base.

A pipe wrench comprises a fixed first portion and a movable second portion. The first portion comprises a holding part, a mounting part disposed at one end of the holding part, and a first jaw disposed at a front end of the mounting part. The second portion comprises an adjustment part slidably connected to the first portion, a gripping part disposed at a front end of the adjustment part, and a second jaw disposed on the gripping part. An adjustment element disposed between the first portion and the adjustment part is used to adjust the position of the first portion. The mounting part has is provided therein with a longitudinally penetrating sliding cavity. The adjustment part is adjustably connected in the sliding cavity. An elastic element used to apply an elastic force to the adjustment part is disposed in the sliding cavity. A seal cover blocks the sliding cavity. The first portion is formed by forging. According to the present application, the pipe wrench is light in weight, is convenient to use, is convenient to machine and manufacture, and reduces the manufacturing costs.

A length is measured from the edge of the first jaw to the second end of the handle portion parallel to the longitudinal axis. A ratio of the width of the first jaw over the length is less than 0.06.

Wrenches commonly known as “pipe wrenches” which include sidewall surface configurations within a channel extending through a housing component of the wrench are described. Also described are wrenches that include one or more shim components that can be positioned in the housing channel. In addition, methods for reducing failure or fracturing of the wrench due to application of high side or lateral loads are described.

A firefighter multi-tool is configured as a standpipe operations spanner tool and comprises several features for adjusting standpipe pressure regulating valves, and performing other functions performed by firefighters. The tool includes a handle portion and a lateral coupling portion. The lateral coupling portion includes an adjustable wrench having a fixed jaw elements and a moveable/adjustable jaw element. The tool can include a socket portion at the end of the handle opposite the lateral coupling portion. A valve cap spanner can be includes on the lateral coupling portion opposite the adjustable wrench.
