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.

The multi-tool wrench is a single tool that provides multiple tools useful by a craftsman. The multi-tool wrench comprises a first tool half and a second tool half that are removably coupled by a quick disconnect. The halves may be decoupled for use in confined spaces or to simultaneously use tools from each half. The first tool half provides an adjustable wrench and two pivoting hex keys. The adjustable wrench has a reversible lower jaw to convert the wrench into a pipe wrench. The second tool half provides a set of three open end wrenches, a pivoting flat blade screwdriver, and a pivoting cross head screwdriver. The open end wrenches and hex keys may be sized to provide common tools needed in a specific occupation or field. As a non-limiting example, the tools may be common sizes used by a welder.

Various offset adjustable wrenches and methods are disclosed herein. The offset adjustable wrench has first and second jaws. The second jaw can be moved relative to the first jaw to grip objects of various sizes. The second jaw can be connected to a sliding element that can reduce or eliminate wobble of the second jaw to improve grip strength. The first and second jaws can be offset from a handle such that a user can grip and rotate an object with the offset adjustable wrench without injuring the user's hand contacting an adjacent surface, such as a wall or ceiling.

An adjustable wrench (1) with a head portion (200), automatically adjustable within its size range. The fastener (80) to be operated is fitted between the fixed jaw (201) and moving jaw (300), the operators thumb pressure released, automatically propelling the moving jaw 300 towards the fixed jaw (200), the use of four workpiece contacting surfaces (202, 203, 302, 303), two within each opposing jaw (201, 300), engaging the four corresponding actual levered faces (83) to each apply a drive force to a hexagonal fastener head 81. The head portion (200) illustrated in section in order to show the gear teeth (403) on the head end (402) of the handle (400) levering closed the moving jaw (300) via its associated wedge-shaped rack gear (312). The handle (400) pivoting at the point PP that the relevant head end gear tooth (403) engages the corresponding rack gear tooth (312) further urging the handle locking teeth (407) into the pawl locking teeth (61) within the confines of the elongate pin hole elongate portion 404 creating a further jaw (201, 300) ratcheting/locking closure mechanism.

An adjustable fastener engaging tool includes a plurality of jaws slidably disposed in a retainer. An actuator engages a driver jaw resulting in the jaws either moving in a first direction to enlarge a fastener-receiving aperture cooperatively formed by the jaws, or the jaws moving in a second direction to reduce the fastener-receiving aperture to grip or release a fastener.
