An apparatus, system and method comprising an improved wrench designed and configured for usage as a hand tool used to tighten or loosen a hexagonal bolt and/or nut is provided. More specifically, the present disclosure relates to an apparatus and method comprising an improved wrench configured to be used without any need to disengage and/or reengage the tool in order to execute its intended function. In addition, the present disclosure can also be categorized as a novel and improved ratcheting wrench having a series of pawls configured to slip past a gear in one direction and yet capture when rotated in the opposite direction.

Various implementations include a surgical screwdriver that comprises a first rotating shaft configured to be rotated about a respective longitudinal axis, a second rotating shaft extending along a respective development axis transverse to the longitudinal axis of the first shaft and having a shaped end tip that can be inserted into the head of a screw, and a transmission member interposed between respective first ends of the shafts to transfer the rotation from the first shaft to the second shaft. The transmission member comprises a pair of hemispherical elements, hinged together about a respective junction axis that is perpendicular to the longitudinal axis of the first shaft, and each hemispherical element is in turn hinged to a first end of one of said shafts.

A modular motorcycle tool kit comprising multiple tool drivers and a plurality of attachable tool components said kit being configured to address most motorcycle repair or service needs. Three drivers include apertures and special step-key shank slots to engage and receive a plurality of tool insert bits and fastener tool heads. The fastener tool heads are coupled to unique step-key shanks which are stronger, more robust, and less expensive to manufacture than comparative fastener tool head shanks. The drivers can be used separately or in conjunction with one another depending on the need of the user. The modular motorcycle tool kit is specifically designed and configured to be an invaluable modular motorcycle tool and at the same time occupy very little space on the motorcycle.

A hollow shaped socket insert adapter rotatively driven by a single socket driver for tightening, loosing, and removing various sizes of nuts/bolts. The socket insert adapter defined by an outer configuration that includes a plurality of outer flat walls having a shape and size to conform to and to fit into a cavity of a socket driver body of the socket driver, the outer configuration defining a plurality of outer flat walls and further defining one or more rounded outer corners. The socket insert adapter further defined by an inner configuration having one or more inner flat walls and one or more rounded inner corners. The hollow shaped socket insert adapter may include a rim on one end that enhances structural integrity, inhibits disengagement with a socket driver, and facilitates manipulation of the socket insert adapter.
