A double-sided, detachable tool includes a first tool half and a second tool half. The first tool half has a first tool head on a first end, a first stepped profile on a bottom surface, and a latch protruding from the bottom surface. The second tool half has a second tool head on its first end, a second stepped profile on its bottom surface, and a latching aperture extending through the second tool half from its top side to the bottom side. The latch is inserted into the latching aperture to connect the first tool half to the second tool half and is removed from the latching aperture to detach the first tool half from the second tool half. The transitions from the stepped profiles to the seconds ends of the tool halves create a substantially flush surface therebetween.

A securing mechanism for releasably securing various implements and shafts to a hand tool, instrument, or device. The securing mechanism may include a button to unlock/lock the shaft relative to the device. The retention feature may include a cam surface. The retention feature may include a biasing member. The tool may include an orientation feature.

A hand tool includes a head and a handle. The head is pivotally mounted to the handle, permitting the position of the head to be changed relative to the handle. In addition, the tool includes a primary locking mechanism and a secondary locking mechanism. The primarily locking mechanism primarily fixes the head relative to the handle in a particular position. The secondary locking mechanism can be used to further lock the head and handle. The locking mechanisms are actuated by movement of a sleeve which is located on the handle.

A screwdriver system can include a primary driver and a secondary driver. The primary driver can include an attachment feature configured to couple to a driver bit socket. The attachment feature can be mechanically coupled to the driver shaft such that torque applied to the attachment feature is transferred to the shaft. The secondary driver can include a driver bit socket at the end of its shaft. The attachment feature of the primary driver can be structured, configured, and oriented such that the secondary driver can reversibly couple to the attachment feature via the driver bit socket of the secondary driver shaft. The secondary driver, when so-coupled, can be oriented with the primary axis of the secondary driver shaft generally perpendicular to the primary axis of the primary driver. In some examples, the primary driver can be a torque wrench.

One or more specific versions disclosed herein is a tool that may include a chassis, a level or level vial, a handle, magnet(s) for adhering to ferromagnetic workpieces and exterior markings.

A torque limiting ratcheting handle for a medical instrument is provided that includes a ratchet shifter, a tool connector, a torque coupler, and a rear power housing. The handle provides clockwise and counterclockwise ratcheting and limits the amount of torque in one direction while allowing for maximal torque in the opposite direction. In one aspect, the ratcheting handle may include a drive shaft removeably connected to a power tool or, alternatively, to a handle grip for manual manipulation.

The main fixed handle optionally incorporates two swivel out arms, which can form part of a three-legged base. When operated thus, the jaws and moving handle point generally upwards from the formed base, the moving handle can now be operated by one hand leaving the other free to position the workpiece. The moving handle can incorporate a further locking switch that can be utilised in both a switchable locking position or non-locking position upon a sprung toothed strut between the handles, at least one of which further incorporates a curved resilient portion in order to provide useful sprung closure of the parallel moving jaws upon the workpiece in the locking method. A lanyard can be optimally attached to the swivel out arm ends to provide the user with a chest mounted portable vice.

A screwdriver comprises a handle including a butt and a shank extending from the handle and including a tip. The butt includes a first indicating element having a shape corresponding to the tip and a plurality of second indicating elements arranged around the first indicating element. Each of the second indicating elements has the shape.

A tool and system for loosening or removing a torque resistant threaded fastener assembly. The system can be used with a bench receiver or vehicle mounted receiver and can be used to loosen “frozen” threaded fastener assemblies. The orientation of the components enables a user to place sufficient torque on a “frozen” threaded fastener. In this way the system enables the user to remove or disassemble a corroded combination (e.g.) a corroded or rusted nut and bolt.

A grip bar for a hexagonal wrench includes a grip, a middle sleeve, an outer sleeve and a rotary member. The grip has an elongate body, a raised portion, multiple first recesses, a head, an elongate slot and a first threaded portion. The middle sleeve includes a first chamber, a first opening, a shoulder and an end hole. The outer sleeve is mounted to the middle sleeve. The rotary member is rotatably inserted in the end hole of the middle sleeve. The first and second threaded portion are connected to each other. The first recesses and the elongate slot respectively accommodate the first section and the second section of a hexagonal wrench. The grip and the rotary member respectively restricted by the shoulder and cannot slip within the middle sleeve so that the hexagonal wrench is firmly combined with the grip and operated efficiently.
